Needles have been found in a punnet of Western Australian-grown strawberries sold at a supermarket in New Zealand.

The Countdown supermarket, a subsidiary of Woolworths, has withdrawn the Choice brand of fruit from sale and is advising customers to cut up strawberries before eating them.

The find follows the spate of contaminated fruit in Australia, which has seen more than 100 cases of sewing needles hidden in fruit reported across all six states.

"Countdown has withdrawn a brand of Australian strawberries from sale as a precautionary measure, and is advising customers to cut up strawberries before consuming them," a statement read.

"Needles were found in a punnet of strawberries sourced from Western Australia, which was bought in a Countdown supermarket in Auckland."

The supermarket said it would withdraw any remaining strawberries from the brand while it investigates.

Draft laws passed by the Australian government last week could see food tamperers jailed for up to 15 years.

"That's how seriously I take this," Prime Minister Scott Morrison said.

"This is not on. We will act to protect, and keep Australians safe.

"Mums and dads and kids have real concerns and fears.

"Some idiot has engaged in an act of sabotage.

"It's not a joke. It's not funny.

"You're putting the livelihoods of hard-working Australians at risk and you're scaring children.

"You're a coward and you're a grub.

"And if you do that sort of thing in this country we will come after you, and we will throw the book at you."
