He was fined $3364.
MPI animal welfare and NAIT compliance group national manager Gray Harrison said NAIT rules are an important part of New Zealand's biosecurity system.
"This importance is reflected in amendments to penalties in the NAIT Act, which have increased the maximum penalty from $10,000, to $100,000 for future prosecutions.
"We certainly take it very seriously. Our ability to trace cattle and deer through the NAIT system is a critical factor in managing biosecurity threats which could have a devastating impact on New Zealand's agricultural sector."
MPI has eight successful prosecutions under the scheme with another eight prosecutions currently before the court.
"MPI will continue to work with OSPRI and the sector to ensure people understand their responsibilities," Harrison said.
"If you don't know what to do, or you need help, call the OSPRI contact centre on 0800 482463."
