NAIT tag management

Buying Tags

OSPRI does not sell NAIT tags. You can buy NAIT tags through your local farm supply store, most vets, or through LIC/CRV.

When you buy tags, they are issued to your NAIT location number and appear in your NAIT account. This makes them easily available to help you register your animals. 

Make sure the tags you buy match your NAIT location number. Most tags have a NAIT location number printed on them. NAIT tags for dairy animals have a dairy participant code printed on them but are still issued to a specific NAIT location.

After you have tagged your animals you must register them by opening up NAIT and entering the animal’s details.

New rules when using tags

A new rule is being introduced from 14 December 2020. You can only use NAIT tags at the specific NAIT location number they were issued for.

What does this mean?

In most cases you cannot take spare NAIT tags with you when you move, or share tags between NAIT locations. In some cases (i.e. for tags printed with a participant code), a tag may be re-assigned for use at a different location – see below.

You do not need to remove or replace any existing tags as a result of this change.


This improves our ability to trace diseases using NAIT tags. If, for example, an animal has not been properly registered in NAIT, disease control experts can look at a tag and quickly identify the animal’s point of origin.

Reassigning dairy participant code tags

If your tags have a NAIT location number printed on them, they cannot be re-assigned. Be careful not to stockpile too many tags if you’re planning to move.

If your tags have a dairy participant code printed on them, they are still linked to a specific NAIT location number, but OSPRI can help you reassign them to a new location in the situations below:   

  • If you move your dairy herd to a new farm, call OSPRI to reassign your tags to your new location.  Do this before you tag your animals. 
  • If a dairy animal loses a tag while at grazing, or is born at grazing, you can tag it with your dairy participant code.  Call OSPRI first to have the NAIT tag re-issued to the grazing NAIT location. See the guide below for more details.

We can re-assign these tags to a new NAIT location number because the participant code printed on the tags refers to a herd, not a location. Call 0800 482 463 if you need to reassign a tag.


How to check you’re using the right tags

If your tag has your NAIT location number printed on it, you’re good to go.
Remember: If you have more than one NAIT number or you move, make sure you don’t share tags between farms.

If you want to check the NAIT location for a tag printed with a herd number or participant code, you can:

  • Log in to NAIT.
  • Find the grey box on the top right hand side of your page (“Look up Animal Or Tag”).
  • Type in the tag’s RFID or visual ID and click ‘Go’.
  • The NAIT number will appear under the “NAIT Number” label
    Some tags issued before 2015 will not have an assigned NAIT number.


Your PICA obligations are

  • All animals need to be NAIT tagged and registered within 180 days or before their first off-farm movement, whichever comes first. It is an offence to move untagged and unregistered animals off your property.
  • Ensure a tag is fitted on your animals at all times and correctly using a NAIT approved tag issued to your location
  • Always tag the animal first and then register the animal in your NAIT account
  • Never remove a NAIT tag without contacting OSPRI first. If you make a mistake and tag animals with the wrong tags you should contact OSPRI 0800 482 463 in the first instance.

Managing tags

Having a tag issued to your NAIT location number, and registering the tag, are two different steps.

When you buy NAIT tags they are issued to you and appear in your NAIT account.  This makes them available to register.  After you have tagged your animals you register them by opening up NAIT and entering animal details.
