The $50 million local strawberry industry is highly regulated through Crop and Food Research and seeds are shipped in from the University of California.
The rogue seeds made it into New Zealand after the Tauranga-based export company failed to recognise they were banned in New Zealand. And even though they were flagged on documentation, MAF failed to pick them up.
A biosecurity officer spotted the seed kits for sale in Christchurch and raised the alarm which led to a nationwide recall.
McNee said there was "some reluctance" to do testing but it was carried out at his insistence. Final results were due this month. He said the biosecurity checks at the border were being improved with training and new systems, including a "red flag" on "risk" items.
Importer Tui Products' Don Forgie said it was a "perfect storm" of events. "No one did this to try and sneak these through the border. We were distraught. New Zealand is very precious to us."
The failure had caused widespread concern in the agricultural industry. Industry group HortNZ chairman Andrew Fenton said biosecurity was a constant worry. "Every day of the year is a scary day for us."
Strawberry Growers NZ chairman John Greensmith accused MAF of trying to "run and hide" over the issue. "We were appalled it got through the system."
