MPI is looking for anything that might be a threat to New Zealand’s Biosecurity. This can be insects such as the fruit fly which would devastate crops and farmers lively hoods if allowed access to new Zealand unchecked by MPI, also microscopic natural threats like PSA kiwifruit disease which likely came through the border. Seeds, dirt, grass and basically anything that is alive or was alive at some stage could potentially be a threat and is taken very seriously by MPI. We highly recommend to save additional fees anything you send to NZ is of the highest standard of cleanliness. Contact Rocket Freight today if you have any more questions.
