Why we need you to report any new pests and diseases.

Early detection of harmful new pests and diseases is a vital part of our biosecurity system. Every New Zealander has a responsibility to be vigilant for and report suspected new organisms.

We need you to be extra vigilant when coming home from overseas or opening international mail because these are common pathways for unwanted pests to enter New Zealand.  

MPI has a dedicated team of specialists to investigate and respond to all suspicious findings. 

It's the law.

New Zealanders are expected to report unusual organisms to MPI. Unusual organisms are those that appear to be something not normally seen in New Zealand.

Refer to section 44 of the Biosecurity Act – NZ Legislation website

Notifiable organisms are those that could seriously harm New Zealand's primary production or our trade and market access. If you spot a notifiable organism, you have a legal obligation under the Biosecurity Act 1993 to tell MPI. If you think you've spotted one, call the pests-and-diseases hotline on 0800 80 99 66.

To make notification of an organism obligatory, that organism has to be made notifiable under the Biosecurity Act 1993. Unwanted organisms only become notifiable organisms once they are included in an Order in Council pursuant to section 45 of the Biosecurity Act. The list of notifiable organisms (issued in 2006) was reviewed in 2009/2010, and replaced by the Biosecurity (Notifiable Organisms) Order 2010.
