Vets and HGP responsibilities

If you are a veterinarian implanting hormonal growth promotants (HGPs), find out your responsibilities under the HGP Regulated Control Scheme (RCS).

Veterinarian's responsibilities

In New Zealand, the use of HGPs implanted into bovine animals is strictly controlled through the HGP Regulated Control Scheme (RCS). You need to be familiar with your full legal obligations under the RCS.

If you are a veterinarian, you need to:

  • record the identity of each animal you implant – there is no specified form for this and you may choose to devise your own form
  • enter the information you have collected into the HGP database
  • keep any paper records generated for at least 4 years from the date of HGP implantation of each animal if you are the supervising veterinarian.

Getting access to the HGP database

To get access to the HGP database, you need to apply for a login and password by emailing

Entering details into the HGP database

For each animal implanted, enter the following details into the HGP database:

  • name of farm, farm owner or person in charge at the time the HGP was implanted
  • physical address and phone number of the business operated by the person in charge
  • agribase farm identification of the farm the HGP-implanted animal came from
  • herd identification number of HGP-implanted animal
  • date of HGP implantation of the animal
  • individual animal identification number
  • HPG product name
  • veterinary practice details
  • name of technician or veterinarian who performed the implant – known as the 'competent person'
  • dated approval of the HGP implantation by the supervising veterinarian.
