17 January 1997
Normal horticultural trade with Australia will resume on 27 January.
Trade restrictions have been in place since May, when Mediterranean fruit flies were found in the Auckland suburb of Mt Roskill. Australia said it would lift
its restrictions after one generation plus 28 days.
A fruit fly ‘generation’ is calculated on formulae involving temperature information for each stage of the fruit fly lifecycle. Fruit fly development
depends on temperature and slows down considerably in cold weather.
There have now been no finds of fruit fly for almost eight months and the Australian Quarantine and Inspection Service (AQIS) has today informed New Zealand MAF that trade requirements can return to normal on 27 January.
Australia will be the first of our major trading partners to lift all restrictions. It currently takes fruit from everywhere in New Zealand apart from an exclusion zone of 15 kilometres radius from the original find site.
Any fruit passing through the zone on its way to Auckland airport must also be in insect-proof containers. Removal of this latter requirement will bring the greatest relief for New Zealand fruit exporters.
Japan and the United States have stipulated that three fruit fly generations must pass without further finds before they will lift their restrictions. Their exclusion zones are 15 kilometres and 7.2 kilometres (4.5 miles) respectively. It will be some months before this criterion has been met.
