Background

Biosecurity New Zealand has been investigating finds of single male Queensland fruit flies between February and July 2019 in surveillance traps in the Auckland suburb of Northcote. A Controlled Area Notice is in place.

Legal controls on the movement of fruit and vegetables had been lifted for Northcote on 22 March 2019. However, they were re-introduced to an area of Northcote on 26 April 2019 following the discovery of a further single male fly in the area. Further single male fruit flies were found within the current Northcote controlled area, with the last detected on 15 July 2019, bringing the total found in the area to ten.

Controlled Area Notice

An area of Northcote remains under a Controlled Area Notice. This restricts the movement of locally produced whole fresh fruits and vegetables (except for leafy or root vegetables) out of controlled areas to help prevent the spread of any fruit flies if there are more out there.

Movement controls on fruit and vegetables

If you live in Zone B (refer to map):

We'd like to thank everyone in the controlled area for their continued cooperation with our fruit fly operation in the area. While the operation is still ongoing, don't move any homegrown whole fresh fruit or vegetables (except for leafy or root veges) and any host garden waste (such as cuttings from fruit trees or vegetable garden cuttings) out of the controlled area. These need to be disposed of in Biosecurity New Zealand provided waste bins. If they cannot fit in the bins, then keep the waste on your property to get disposed of through appropriate movement permits, or be chipped.

You are free to move commercially-purchased fruit and vegetables (such as fruit and vegetables bought at the supermarket) out of the area.

If in doubt, don't take it out.

Fruits and vegetables that are affected

All whole fruits and vegetables must meet the requirements of the Controlled Area Notice. Exceptions are:

  • leafy vegetables
  • root vegetables
  • cooked, processed, preserved, dried, frozen, and canned fruit

We have brochures in English and other languages with information and guidance about movement controls. 

Information for people in the controlled area making packed lunches

If you live in the controlled area (refer to map) and you're preparing lunch for work or school, you can still include home-grown fruit and vegetables, just make sure it's cut up and you can't see any larvae in it.

If you find larvae in fruit or believe you have seen a fruit fly, call 0800 80 99 66.

Information about Export Restriction Zones

We have established an Export Restriction Zone (ERZ) of 3.2km around the controlled area. This means export consignments of Queensland fruit fly host material must meet additional requirements to move through the ERZ and be eligible for export.

All Queensland fruit fly host material destined for export and travelling through an Export Restriction Zone must be contained in an insect-proofed environment and some additional documentation provided.

We've prepared the following information and guidance about the Export Restriction Zone and transit requirements.

Queensland fruit flies are about 6 to 8 mm long and are reddish-brown coloured with yellow markings.

If you find larvae in fruit or believe you have seen a fruit fly, call 0800 80 99 66.

If you live in Northcote, find out if you're in the controlled area. If so, you will need to follow legal restrictions around movement of fruit and vegetables. Remember – if in doubt, don't take it out.

Risk to New Zealand

Queensland fruit fly would jeopardise a horticulture industry worth $5 billion a year in domestic sales and exports.

  • 80% of New Zealand's horticulture crops are susceptible to attack by Queensland fruit fly.
  • Fruits and vegetables they attack become inedible.
  • Any fruit and vegetables would be subject to trade restrictions.

Keeping them out

To keep Queensland fruit fly out, New Zealand:

  • imposes tough requirements on imported produce
  • checks passengers, luggage and freight at the border
  • has had a dedicated trapping programme since the 1970s.

The traps are an early-warning system, telling us if flies have arrived, so we can eradicate them.

Surveillance

Biosecurity New Zealand's surveillance programme watches for 100 species of fruit fly, including the Queensland fruit fly.

  • More than 7,600 traps are set around the country.
  • Pheromones are used to lure flies into the traps.
  • Most traps are placed near airports, seaports, and densely populated areas – where flies would most likely enter the country.

Trapping runs from September till June, when fruit flies are active. Any catches trigger a response similar to the current response. If a breeding population is found, insecticide treatments are used to get rid of it.
