Minister of Agriculture and Biosecurity David Carter conceded at a media conference on Friday afternoon that the Psa infection threatening the Bay of Plenty's kiwifruit industry could be 'stuck” in the region.

He announced no other orchards outside the Bay of Plenty have tested positive for Psa.

Zespri CEO Lain Jager, Minister of Agriculture and Biosecurity David Carter and NZKGI president Peter Ombler speak at Friday afternoon's media conference.

David says officials are getting more information about the bacterial infection and have concluded it is very difficult to eradicate, mainly because it is an airborne infection and can also be easily transferred via water and orchard equipment.

Leaders within the kiwifruit industry have urged the government to wait a few more days before announcing if eradication is impossible.

A total of six orchards within a 10 kilometre radius near Te Puke are under biosecurity controls. Only three have tested positive for the infection.

'The good news for me is that we are not getting positive samples from other regions,” says David.

'No other kiwifruit growing regions in New Zealand have submitted positive tests, so today we are only dealing with these problems in the Bay of Plenty.”
