Northland locals are being urged to do their bit to fight the invasion of a potentially hazardous foreign pest.
A major biosecurity operation is underway in Northland after Myrtle rust was discovered in pohutukawa seedlings at a nursery in Kerikeri.
Myrtle rust is a significant disease of plant species from the Myrtaceae and has been spreading rapidly around the world in recent years.
It poses a serious threat to a range of our most cherished plant species - including pohutukawa and rata - severe infections causing plants to die.
Plants that are also important to our honey industry, such as manuka and kanuka, could also be affected, which could severely impact on New Zealand's annual $300 million of honey exports.
Other at-risk species include feijoa, gum and bottlebrush.
Primary Industries Minister Nathan Guy told Mike Hosking there's a controlled area notice at the nursery in Kerikeri and the seedlings have been destroyed.
But he said MPI wants to hear from anyone who's bought any trees - particularly of Myrtle variety - in the last month or so.
"From that nursery or from other nurseries in Kerikeri, please inspect your trees and let MPI know if you see anything that looks like Myrtle Rust."
Guy said Myrtle Rust is air-borne so it was only a matter of time before it arrived here.
He said it took three to five years to impact the Manuka species in Australia.
"We'll be working very closely with the bee industry to do as much as we can to inspect all of the Manuka and Kanuka in Northland".
Guy said the Government will do everything possible to get rid of the disease, but it will be challenging.

Minister of Conservation Maggie Barry is also encouraging Kerikeri locals to support the biosecurity work.
"People should engage with this and be careful about what they pick and how they move plant material around the affected region," she said.
Meanwhile, New Zealand First leader and Northland MP, Winston Peters, said the Government was warned, and has instead been incredibly arrogant on the issue.
He said a Crown Research Institute made six recommendations to help prevent this in 2010 - and the Government didn't action a single one.
