Nervous growers are weighing up their farming futures as the strawberry contamination crisis forces New Zealand's major supermarkets to stop selling the fruit from Australia.
Police are investigating after metal pins were found in punnets of fruit in five Australian states.
Federal Health Minister Greg Hunt has also ordered the food safety watchdog to investigate Queensland's handling of the strawberry spiking saga.
He's directed Food Standards Australia New Zealand to investigate whether there are supply chain weaknesses or systemic changes needed.
"At the end of the day, the job is very, very clear. Protect the public and keep them safe," he told the ABC today.
Both Foodstuffs and Countdown (owned by Woolworths) - which between them control nearly the entire New Zealand grocery market - today announced they had stopped sending out Australian strawberries to their stores.
In separate statements, both said while none of their products had been affected by a major recall in Australia, they wanted to reassure customers.
Countdown said it had stopped ordering any further imports of Australian strawberries, while Foodstuffs had halted distribution.
New Zealand imports the fruit from Australia when it's out of season, from April to September, and both chains say the Kiwi product will be on shelves shortly instead.
The announcement comes as needles were found inserted into more strawberries in South Australia and New South Wales over the weekend, adding to incidents across the country and prompting fears of copycat behaviour.
Vice-president of the Queensland Strawberry Growers Association, Adrian Schultz, says what started with a single act of "commercial terrorism" has brought a multi-million-dollar industry to its knees.
"I'm angry for all the associated people, it's the farmers, the people who supply them, the packaging people, the truckies with families to support, who suddenly lose their jobs ... it's far-reaching," he said.
Cabinet minister Christopher Pyne says he understands why New Zealanders are baulking at Australian strawberries.
"I hope we catch them and prosecute them and they spend a lot of time behind bars, because that's what they deserve," Mr Pyne said.
"They have behaved shockingly badly and they are affecting the strawberry industry in Australia but also now the exports to New Zealand."
Nationals frontbencher Andrew Broad has blasted the culprits as "low-life scum".
Coles and Aldi supermarkets have pulled all strawberries from their shelves, except Western Australia, as a precaution.
Berry Obsession, Berry Licious and Donnybrook Berries have recalled their strawberries nationwide.
A health warning to throw out or cut up strawberries remains in Queensland, NSW, Victoria and South Australia.
