Commodities killing exports?
There has been a view that high commodity prices are reducing the impact of the high New Zealand dollar. This is despite the fact that commodity exports only make up a quarter of our exports and there are numerous other reasons for the dollars’ appreciation.

This graph shows that only 25 percent of New Zealand’s exports are solely reliant on commodity prices. For the rest a high exchange rate means lower returns and therefore less investment in new products and capacity expansion.
Economic commentator Neville Bennett has described this as New Zealand’s version of the ‘Dutch Disease’ in an article for Interest.co.nz:
“We have a high dollar which is not only encouraging our industry to migrate overseas, but which is also making imported goods very cheap. Our manufacturers face unfair competition because the exchange rate is too high.
The consequence is that, like many western economies, New Zealand is hollowing out and losing a vital part of its economic structure. Many skilled people in the secondary sector are being displaced and the sad fact is that if the dollar ever plunged again the fitters and turners, machinists etc. will have lost their skills.
There is a classic case today where the people making railway carriages in Dunedin are being laid off because imported carriages were marginally cheaper. If the dollar was fair value we would most likely have kept their jobs, skills, and demand in Dunedin would be higher. We will have some difficulty in carriage making in the future.”
Bennett’s comments are on the money. Any sustained period with a high dollar will inevitably lead to either New Zealand firms moving offshore or these firms losing business to offshore competitors. He also presents a plan for dealing with the problem suggesting a capital gains tax, a financial transactions tax and capital controls as methods to deliver a more trade based value. These comments are worth a read.
