"We take non-compliance seriously because of the potentially devastating effect these threats can have on industry and communities," Tuckwell said.
"Tagging the animals is only half the job, they must also be registered into the system.
"We can't afford complacency. Our message to people with animals which come under the NAIT scheme is that we all need to do our part to protect New Zealand's biosecurity."
The NAIT Act was amended in late 2019, increasing the maximum penalty tenfold to $100,000.
Up to 2018, only about 60 per cent of tagged animals were being registered before first movement. Since 2019, MPI and the Operational Solutions for Primary Industries (OSPRI), which maintains the NAIT database, have renewed efforts to improve compliance, and the compliance rate was up to 90 per cent by the end of 2021.
People in charge of animals who are unsure about what they need to do should visit the OSPRI website ospri.co.nz for details.
