Angry New Zealand growers have declared war on Australia in a bid to gain access for their apples.

A NZ-wide group of growers are warning of protest action and boycotts throughout the country, and possibly even in Australia, starting next month.

A massive grower led protest march to New Zealand Parliament House and the Australian High Commission in Wellington will be held on June 22.

Action Group member John Bostock said apple growers throughout New Zealand are building an army and are urging the New Zealand public to show their support by not buying Australian fresh produce.

He said: "New Zealand imports Australian tomatoes, melons, pineapples and other products and yet we can't ship our apples to Australia.

"To help win we need the New Zealand public on our side. Australia will not listen to us on our own.

"Consumer choice is our greatest weapon. We are asking all Kiwi's to make a stand by choosing not to buy Australian fresh fruit and vegetables."

He said they were also calling on the supermarkets to voluntarily stop stocking Australian fresh produce.

"We need to hurt Australian industries such as tomatoes, melons, grapes and grain industries so they understand what it's like to be shut out of a market and the impact on their livelihoods.

"The Australian public also needs to know they are not getting a good deal and are being served up old fashioned and poor quality apples. New Zealand growers can offer a choice of new and exciting varieties offered a range of taste profiles."

Australia has blocked New Zealand apples for 85 years, citing the fear of the bacterial disease fireblight as the reason.

However last year the World Trade Organisation ruled on scientific evidence that mature apples do not carry the disease.

The prize is worth fighting for, Mr Bostock said. Australia currently eats only 9kg of apples per person - the lowest in the western world - compared with New Zealanders who eat 18kg per person.

"With our quality and reasonable price, we can move Australian consumption to 14kg per person," he said.

The action group said it wants the NZ government to take a tougher stance against what they see as Australian bullying.
