The Ministry for Primary Industries is improving biosecurity systems at the border after a report highlighted shortcomings.
The Ministry (MPI) commissioned consultancy firm Grant Thornton to review its cargo systems in 2019.
The Ministry said this was used as an internal resource and it had now released the findings publicly.
The report said while New Zealand's biosecurity system has previously operated effectively, it was under threat. It said this was evidenced by recent major events such as Mycoplasma bovis, Psa, and fruit fly which had billion-dollar effects on the economy.
