Have your say

The Ministry for Primary Industries (MPI) is seeking your feedback on the proposed changes to the Import Health Standard (IHS) for Nursery Stock: 155.02.06. The changes are to the import requirements for management of regulated plant mites under 'Basic conditions' in part of the IHS – pesticide treatments for whole plants and cuttings.  

The consultation will run from 28 February to 9 April 2020.

Full details of the proposed changes are in the consultation documents.

What's being proposed?

  • Changes are proposed for chemical treatment options to manage regulated plant mites on imported whole plants and cuttings under Basic conditions of the current Import Health Standard for Nursery Stock 155.02.06 (part ‘Pesticide treatment for whole plants and cuttings).
  • We are proposing multiple treatment options using different chemicals either in combination or as standalone chemical treatment. While various new chemical options are proposed, Abamectin and Dicofol are still remaining.
  • MPI proposes to remove specific measures for Tetranychus kanzawai (Kanzawa spider mite) from the following 6 schedules in the current Import Health Standard for Nursery Stock 155.02.06. Those schedules are Calanthe, Dahlia, Tricyrtis, Verbena, Hydrangea and Gentiana.
  • Specific measures for Tetranychus kanzawai are no longer required because the proposed measures for a generic treatment (part b ‘Pesticide treatment for whole plants and cuttings) for all regulated plant feeding mites are also effective in managing mites belonging to the genus Tetranychus, the spider mites.
  • A new treatment combination (rate/time/temperature) for current Methyl bromide fumigation option to manage plant feeding mites on whole plants and cuttings in the same part of the Import Health Standard for Nursery Stock 155.02.06 is proposed.

Next steps

After we have considered all submissions there is a 10 day period which provides submitters with the opportunity to examine any changes to the IHS which have resulted from the consultation. An independent review (under section 24 of the Biosecurity Act 1993) may be requested in this period if a submitter considers scientific evidence they raised during their submission has not received sufficient consideration. If there is no review, the IHS becomes final after 10 days.

Submissions are public information

Any submission you make becomes public information. Anyone can ask for copies of all submissions under the Official Information Act 1982 (OIA). The OIA says we must make the information available unless we have a good reason for withholding it. You can find those grounds in sections 6and 9 of the OIA. Tell us if you think there are grounds to withhold specific information in your submission. Reasons might include, it's commercially sensitive or it's personal information. However, any decision MPI makes to withhold information can be reviewed by the Ombudsman, who may require the information is released. 

Legal background

MPI must consult with interested parties in accordance with section 23 of the Biosecurity Act 1993 (the Act) and MPI's consultation policy before issuing or amending (other than of minor or urgent nature) import health standards (IHS) under sections 24A and 24B of the Act.

An IHS specifies import requirements that must be met either in the country of origin or of export, or during transit before biosecurity clearance can be given for the goods to enter New Zealand. MPI must ensure that these requirements are technically justified and provide an appropriate level

of biosecurity protection.
