The Ministry for Primary Industries is changing the way secure documents such as OAPs, registers, and pest lists are accessed on their website.
Now each person's RealMe (https://www.realme.govt.nz/) identity will be used to provide secure access across the MPI site.
If you already have password access to the MPI site, then you should have received an email from MPI advising of this change, and they will update you on the implementation date for RealMe access.
If you already have a RealMe login you will be able to use this for the MPI website. If you don't have a RealMe login you can sign up for one at https://www.realme.govt.nz/
