Leigh Catley from Horticulture New Zealand points out this month’s Grower Magazine that New Zealand now imports $2 billion dollars worth of food. I calculate that to be roughly 500 cans of tinned food each. Actually a lot of that imported food is ‘fresh food’, not tinned. Doesn’t that seem excessive in a country that, if any country could, should be able to feed itself? As Catley points out:
“Last year New Zealand imported 535,000kgs of jam and marmalade from China – a 420% increase on the 102,000kgs imported in 2003. In that time the average cost of the imported product has increased from $1.34 per kg in 2003 to $2.33.”
And, why for instance did we need to import $70 million worth of meat from Australia? Was that some sort of humane gesture on our behalf towards the sheep and cattle on our farms? (Let foreign sheep take the bullet this dinner time.)
More likely it is too hard for us to work out what is the New Zealand meat and what is the Australian meat? Horticulture New Zealand’s Chief Executive Peter Silcock says mandatory country of origin labelling (MCoOL) is the only way to ensure that consumers get to make the right choice for them, “whether their purchase decision is based on product origin, the price, safety concerns, political beliefs, nutrition needs or just plain old flavour preference”.
“Ironically, the Watties Chef Jellimeat petfood cans do feature the information on the label “Made from New Zealand Beef.” They are happy to be specific on a petfood can, but not on a can for human consumption!”

on the trolls and those who are unable to keep on topic
Maybe this is muddle headed but I feel that globalisation will end in tears for NZ as we will be left (as always ) paying for the short fall in our exports by exporting our land to foriegners (and eventually the Chinese). Hendo and his Act friends will go to their chateaus in Portugal and drink wine.
Do National or Labour have any plan to retrain the “unskilled”?… I know from personal experience there are an awful lot of people who didn’t get a trade and wished they had. There are also an awful lot who buy businesses (eg Rent A Car) and find everyone and his brother is doing it. The media are big on good news, concentrating on the tree on the hill but ignoring the mud all about.

While obviously global capitalism is rather illogical in many of the way it works, and this means you get many, many perverse results, it’s also the case that there is a huge logic to having different countries and lands specialising in producing different commodities.
Many parts of the world are much better suited for growing different sorts of food, so it makes perfect sense for the different countries of the world to grow these different foods and trade them with each other. It would be totally silly to expect New Zealand to grow all the food that it consumes. That would be incredibly inefficient and expensive – not to mention environmentally unsound.
The logic of Frog’s above complaint is that the Greens favour NZ (and all the other countries of the world) becoming fortresses in food production. Such a policy is indicative of the backward style of the Green Party in having policies that are actually pretty bad for the environment. It reminds me of all the unthinking Green groups in Europe that object to NZ butter coming to their side of the world due to “food miles”.

Oh JH I thought you wrote “retain” and I was going to say Labour and the Greens definitely have a plan to “retain” the unskilled while chasing away the skilled people that could save this country from the export of our most basic natural resource of all.
But back on topic it is totally bizzarre that we import any food. One of the reasons of course is that food exporters are usually peasant economies and hence it is cheap. By giving tax cuts we could actually reduce labour costs and produce more of it here. As other countries catch on to the protectionist advantage of GW/food miles we might even become a net importer of food and exporter of land as JH says. Or we could all just give up and go basket weaving like Kedgley wants.

the Greens do not advocate banning food imports, stopping international trade in food, or any kind of protectionism as you all seem to be riffing on. All we are asking for is mandatory labelling of food products for their country of origin so that those consumers who choose to buy NZ can know which foods are from NZ. Is that really too much to ask? What possible objection can you have for that?
P.S. 70% of our balance of payments deficit is from purchase of oil. If you want to stop NZ being forced to “export land” then the answer is clear – stop driving.

Unfortunately not as simple as that stuey. Nz’s current oil production exceeds its demand, but the oil is shipped to Australia because Marsden point can not efficiently process it. Unfortunately also NZ’s oil production is majority foreign owned. All of which may add weight to your argument, but yeah.

Country of origin labeling is just the latest in a long line of unnessesary regulation on consumer goods advocated by the greens. Who suffers most? Those who are struggling as it is to make ends meet. Those on the minimum wage whose interests the green party claim to care about. While most can afford to pay a little extra for all the regulation, people who are stuggling, maybe raising a family will take notice at the ensuing price increase. To them this will be yet another stupid gymic.

You what? How on earth does CoOL increase food costs? If there did have to be an increase in costs it would be infinitesimal. What are all the expensive things that food manufacturers are going to have to do that they are going to have to pass on to their customers? Go on, tell me what they are?
Also, food manufacturers are very reticent about passing on costs – you always see them try to swallow up increases in commodity or transportation costs and only once their margins get too slim do they increase costs.
Any possible increase in costs to the manufacturer caused by CoOL are completely dwarfed by the recent huge rises in transport and distribution costs and world food prices (e.g. because of bio-fuels)

Stuey, You are not quite correct that 70% of our balance of payments deficit is from purchase of oil. When Saint Michael grabbed the purse strings we didn’t have a trade deficit worth mentioning. Now it is over 6 billion a year. Just under half this amount is from the increased cost of oil.

It is especially worthy of note that for the last two items the percent increase in value of exports was only half that for imports. In the case of foodstuffs that could mean that pretentiuos twats with more money than sense have taken to buying stupidly expensive “designer label” food and drink rather than the buy the cheaper and tastier kiwi imitations.
In the case of metal it is simply that aluminium hasn’t risen in value as much as steel and other metals. Perhaps the aluminium industry was able to increase production to cope with China better than the steel industry.
It seems we will have to stop driving on playstations as well as on real roads.
By “export land? do you mean selling it to foreigners or mortgaging it to foreigners. IMHO the latter is what we are really doing and it far more dangerous than selling it outright.

Your oil production numbers are all out of whack. we are nowhere near matching local production with demand. We consume about 120kbpd, production last year was only 18.5kbpd. That has changed a bit this year with Tui coming online and getting up to 50kbpd but it is still ‘only’ 50% of demand.
The reason they export most of the crude is because it is light and our market is too small to absorb the narrow range of products you can efficiently make with it, and they make more money exporting.
That is a legacy of Think Big, as NZRC was configured to best make large quantities of jet and diesel out of lower cost heavy crudes. Light crude is better for petrol, but that was intended to come from the Motonui gas conversion plant. That’s why we import a lot more refined petrol than diesel. The bigger, more diverse refining industry in AUs can better absorb and efficiently process the quantities we produce.

Country of origin labelling can’t be seen as a trade barrier. Often enough it helps sell the product. Earlier this week I was specifically looking for Belgium chocolate. It would only act as a barrier if they have something to hide.
It shouldn’t add to the cost of most products, since they are labelled anyway.
I for one support this move.

It won’t be any form of nuclear power yet invented, because we don’t have enough uranium. It won’t be solar panels, because there’s a limited supply of the trace metals to make them from.

kahikatea,
Much of it could come from hydro, but only by breaking away from the traditional mindset. For instance, many micro-hydro techniques can be scaled up to utilise the waste water from existing hydro generation.
I think modern wind turbines are mostly made from composites, although I could be wrong. A number of researchers have proved the feasilibility of roof-top turbines. We have millions of rooftops to put them on.
I agree it wont be nuclear.
A small amount will come from solar panels but a big amount can come from solar thermal substitution of existing electric hot water and space heating.
Tidal, wave and geothermal generation have enormous potential in this country.
It just requires the right motivators to make it happen.

Also I fail to see how this is going to decrease the transport cost. That realies your assumption that as soon as we get country of origin labeling everyone in New Zealand is automatically going to start buying the kiwi-made stuff, something i doubt. It only works in Australia because everyone there is patrioic, and believes in Australia. In John Howards consession speech he said “Australia is the greatest country in the world”. That attitude simply doesnt exist in New Zealand, when was the last time we heard an New Zealand politician say that?

There are several forms of solar panels. You are thinking of photovoltaic panels – direct conversion from sunlight to electricity. However solar panels are also used for water heating. Coupled with reflectors, the water can be turned to steam. With steerable reflectors, the heat can be used to generate electricity using relatively conventional means – very similar to those at geothermal plants. In fact, the geothermal plants might be able to use solar heat by day and geothermal heat by night.

However I’m well aware of the makeup of the oil production profile in NZ, and the temporary nature of Tui. I’m also aware of why Marsden does what it does. What I was actually trying to allude to was the absurdity of trying to say that we could stop importing petroleum and petroleum products: Our economy would collapse, because our remotely distributed population would have no way of fertilising their crops, no way of transporting their goods to a marketable point, let alone nationally or internationally. Its true we could all build mud huts and sing songs around the campfire and grow bountiful volumes of Kumara and Watercress and eat Kiore and die at the age of 42 and have a very insignificant carbon footprint. But we are human beings, we love luxury, we love cheap power, we love the great things that are made with industrial chemicals, we are consumed by a lust for consumption that will ultimately, inevitably lead us to a point where everything will collapse. It will have been beautiful though, in a way.

andrew,
I would suggest, from the correlation between the level of foreign debt and median house prices over the last 40 years, that this country is closer to calamity than any of the experts will ever let on for fear of triggering the disaster. The Reserve Bank classifies foreign debt as either corporate or government. This makes it impossible to work out how much of the 150 billion in corporate debt is actually mortgages and credit card debts sold by New Zealand banks to foreign finacial institutions. That’s one h*ll of an exposure to a global confidence collapse as recently seen with the global repercussions of the US sub-prime collapse. 150 billion is equal to one million $150,000 mortgages.
I agree that that balance of payments is not a meaningful economic indicator & should be ignored in policy making. At least the goods and services part is. The foreign indebtedness part is probably a key indicator on it’s own.

And we have plenty of steam traction engines still chugging around from one vintage machinery fair to the next, so farmer’s will still be able to plough and harvest. Problem solved.

Reading the files from Emerald’s link:
http://homepages.ihug.co.nz/~demon/windy.html
it seems to me that Sean Cox is overstating his case a little.
I can’t see why he uses a figure of 0.1 tonnes of CO2 displaced for each MWH (MegaWattHour) for the Te Uku wind project and 0.4 tonnes per MWH for the other projects. Even if a wind farm displaces mainly hydro generation, that hydro generation can then be used to displace thermal generation, so the figures for thermal generation alone should be used.
When it comes to paying for it in overseas currency, Sean Cox is ignoring the possible balance of payments effect of the energy generated itself. If a wind farm (or other renewable generation) displaces power generated from gas (directly or indirectly) then that gas can be used in place of imported fuels or exported. Assuming that plans to import natural gas (methane) are quashed, we can use any gas saved instead of petrol by a simple CNG conversion of some of our vehicle fleet. (If natural gas is imported, any gas saved is a direct reduction in imports.) If the displaced generation is from coal, then we can reduce coal imports or increase coal exports accordingly.
(This includes gas or coal displaced at the point of use, if electgricity is used for heating instead of gas or coal.)
These arguements are important because they will apply to any renewable sources of electricity.
I am intrigued by his suggestions of using tree thinnings as a source of power. That certainly sounds like a possible alternative to gas fired generation and running Huntley on charcoal would be more environmentally sound than running it on coal.
If his figures on the wind speeds are correct, someone hasn’t done their homework properly on the Te Uku site.

I see you linked to my Te Uku files.
Please comment on them and I will try to answer any questions.
Please make allowance that I am an aerodynamicist and environmentalist. Not an Electrical Engineer.
I do know about wind turbine grid integration.
Trevor29:Remember this is a submission in opposition!
There was no problem making it look bad. Just the opposite, this is optimistic. The median numbers are so awful they would not have been credible.
The electricity replacement model was done assuming 2GW peak wind output available.
In this case I believe the coal stations HAVE to be on-line, because the hydro stations cannot react to load changes fast enough. This is why Huntly was built in the first place. They are the first choice for load stabilization because they are the cheapest.
As more wind power is bid it will replace others in the order of cost so it will be
Gas Turbines, geothermal, hydro, in that order. Neglecting the minor ones.
This is all for a Wind turbine without it’s own co generation, that is a more complex model.
As far as I’m aware if there is not a massive grid upgrade in NZ there will be no replacement of coal generated power by wind power if more than about 1.2 GW rated output of wind turbines is installed.
The key to getting these coal burning station out of it is to have renewables that are the equivalent to coal stations. Hence my focus on wood chip.
That 0.1 number is probably wrong, it is just the official MFTE number for Maui gas.
The other projects are given a better number because they DO actually replace coal stations as load stabilizers. It is just an average, the actual number is indeterminate.
The payment calculation was really to compare with the other options and give some kind of objective measure.
It is unfortunate that the time I had to do this was not enough to do the detail for the other projects.
I agree that this kind of ‘where does the money come from’. should be done for all energy projects.
The very high cost in foreign exchange, the high capital cost and the very low domestic content of imported wind turbines just make them bad by this measure.
Why hasn’t NZ already got several Wood chip power stations?
This technology is a ‘no brainer’ for NZ.
Running Huntly on wood chip is not “more environmentally sound than running it on coal.” Is is about as green as you can get.
Huntly is already built and payed for, closing it down rather than running it on ecologically positive and renewable charcoal would be an act of stupidity.
Also if the Huntly site had a wood gasification unit the CSG unit could run on the gas from the wood and the charcoal remains would fuel the steam turbines.
The Raglan area really is not windy.

Sean, I can’t see how your wood chip proposal could work with the dual-fuel furnaces used at Huntly.
From http://www.schoolgen.co.nz/thermal_energy.aspx
“Coal is put into several large grinders, crushed into a fine powder and blown into big boiler furnaces. If gas is used, it is piped into the furnaces and then burned in the boilers.”

Sean, An alternative use for your proposal would be to replace coal as the source for indutsrial and hospital boilers in the South Island where 90% use coal, chipped rather than powdered. Most North Island steam boilers use gas because it’s readily available and allows unattended start up and shut down.

Kevyn, I had a discusion with one of the managing engineers from Huntly last year about the main steam boilers. They should run on charcoal (derived from wood chip) without much modification but are unlikely to be able to run on wood chip inself without serious work.
CSG unit could run on gas from a wood gasification plant and this would provide about 1/2 of the charcoal needed for 1 boiler.
More charcoal could come from microgen or another CSG unit.

From http://www.viewsofscotland.org/snp_conference/PeatAudit-Guide.pdf
“The CO2 emissions arising from electricity generation depend on the fuel used: nuclear power has
almost zero emissions, coal firing is usually taken as 0.86 tCO2/MWh and gas as about 0.3
tCO2/MWh. The generally accepted grid average is 0.43 tCO2/MWh”
Another reference is
http://www.ref.org.uk/images/pdfs/Whiteco2.pdf
which gives values of 0.43 to 0.86 (the latter figure is for coal) and gives some of the complexities involved with determining these figures.
That value of 0.1 looks decidedly unrealistic as a figure for electricity from gas generation. It looks more like a New Zealand grid average, which could be out of date since we have used more thermal power in recent years. In any case, the value for displaced generation should be somewhere between the gas and coal figures, i.e. around 0.4-0.8.
Trevor.
PS: the figures are tonnes of CO2 per MegaWatt-Hour or kilograms of CO2 per kiloWatt-Hour, which are equivalent.

I disagree. Hydro stations can react quickly to load (or supply) changes. In fact, the frequency regulating station is usually a hydro station – that’s all we’ve got in the South island. Coal-fired stations can’t be brought on line quickly and can only react quickly if they are already fired up.
I believe that Huntley was built to meet the total annual load and the peak demands of the North Island, rather than for short-term grid stability.
This doesn’t really affect Sean’s argument. Wind power is useful, but has its problems and the most obvious one is its short term variability, which on one site can be from nothing to full power or vice versa in 15 minutes or so. Spacial diversity helps – i.e. installing wind farms in different areas so they are affected by different weather. However you still need enough despatchable power to meet the demands, and wind power isn’t despatchable.

Sean’s submission mentioned that Stuart Island has areas with average wind speeds above 9 metres per second. Given that they use diesel generators running off imported fuel and pay about twice mainland prices for electricity, they would appear to be ideal candidates for alternative energy resources such as wind, wave and tidal flow (through Foveaux Strait). Do they have any of these? Are there any plans to use wind, wave or tidal power?

Couldn’t agree more Kevyn, except the Chathams doesn’t have a tidal resource that I know of – perhaps solar instead.

Certainly solar-thermal would be viable. Perhaps conventional windmills with compressed-air storage to run their existing deisel generator sets?

Question for Sean Cox:
In your submission, you raised the question of how to pay for the foreign currency.
I commented above (2 Dec 2007) that the electricity generated by the wind farm could generate foreign currency. I suggested as an example that any saving in natural gas use could be used to substitute for imported fuels. However a more direct way of earning foreign currency is by way of our aluminium smelter, which in dry years has been forced to cut back production of aluminium, which would have otherwise been exported. In addition, although we don’t import or export natural gas (at the moment), I believe we do export products made from natural gas, namely ammonia and/or urea. (Urea is made from ammonia, which in turn is made from hydrogen, which is made from natural gas, all at the Petrochem plant in Taranaki.)
Do you agree with this line of reasoning, or have I missed something?
Of course, for this to be significant, the wind farm would have to generate a respectable amount of electricity, which the Te Uku wind farm might be struggling to do.

“What Price Paradise?
So the Government says it wants to make it harder for New York bankers and Canadian music stars to buy a slice of heaven down under, the truth is, it has no intention of actually stopping such land sales, and land is only a fraction of what is being flogged off shore.
New Zealanders are rightly upset that the world’s wealthy are buying up so-called trophy properties, including our high country, beach and lake fronts, so they can escape from an increasingly overcrowded, polluted and violent world. Kiwis paying high rents or wanting to buy a home are also frustrated that residential property prices are artificially inflated because small-time foreign investors want to get rich at their expense…”

Many people would look at the above document and think oh but they don’t really understand the economy. People rate economists with surgeons and the deeper they are in the system (surrounded by money) the more credibility they are deemed to have. To convince more people your gonna have to go deeper into the counter arguments. I think we need to have a drive to get more people improving their knowledge of economic issues. Confucius once noted that without a strong (well reasoned argument) a person can do little better than mimic a fish out of water.
It seems to me that as a country we have no plan (although the free marketeers would probably conclude that we don’t need one). In the 1960′s and 70′s we were building dams. Now we are selling off as much land as we can to foreigners, and talking about the advantages of a greater population… (and the need for nuclear power plants) with little though to exporting or comparative advantage.
