Applying for a type approval

Check our approvals database first

Before you consider applying for a type approval, check our approvals certificate database to make sure there are no existing approvals covering the use of your weighing/measuring equipment.

Search the approval certificate register

Types of application

An application for the approval of weighing or measuring equipment will generally fall into one of the following 4 categories.

1. Application for in-situ type approval

This type of application may be required when approved components are used to construct a complete weighing or measuring instrument. It may involve the instrument being subjected to an on-site performance evaluation (examination).

2. Application approval based on an overseas approval

If a type of weighing or measuring equipment has already been granted International Organization of Legal Metrology (OIML) approval by an overseas weights and measures authority, it can be submitted for partial type evaluation (examination) in New Zealand. This determines its suitability for approval in New Zealand.

In order for us to accept an approval application based on overseas approval, the overseas weights and measures authority that issued the certificate must:

• be a full member of the OIML
• be listed on the OIML website as an issuing authority for that particular category of instruments, and
• have given that approval in conformity with the appropriate OIML International Recommendation(s).

3. Application for variant to an existing type approval

This type of application is required when an instrument that has already been approved is modified, and the changes affect the technical and metrological characteristics of the instrument — and probably its weighing or measuring performance.

The instrument will require either full or partial type evaluation to determine if it still meets the performance requirements of the existing type approval.

4. Application for amendment to an existing type approval

This type of application is required when minor (administrative) changes to the Certificate of Approval are requested, and these don't affect the technical and metrological characteristics of the approved instrument.

An application for amendment can only be made by:

• the original submitter of the approval application,
• the equipment manufacturer, or
• an internal memo from Trading Standards.
