"The stats show biosecurity fines increased by more than 50 per cent between 2014 and 2016. With the busy summer period yet to start, we are expecting to see another increase this year," said MPI passenger manager Craig Hughes.
"The rise is partly due to the increased numbers of visitors, but also to the tough stance we're taking on people that put New Zealand at risk. We're now more likely to issue a fine than give a warning."
He said failing to declare because you forgot, were tired from travelling, or did not know the rules was not enough to avoid a fine.
"The $400 fines are a stern reminder to air passengers who unintentionally fail to declare biosecurity risk goods such as fresh fruit. Where there is deliberate intent involved, passengers can face prosecution or be refused entry into New Zealand," said Hughes.
Travellers entering the country needed to declare or dispose anything that could have a biosecurity risk before entering New Zealand, he said.
