A trial is under way to streamline border processing for low-risk travellers and traders, starting with those who fly across the Tasman.
While in its early stages, Customs Minister Nicky Wagner said trusted passengers who regularly travelled the route would be involved in the trial.
They would supply extra information to border agencies and in return undergo less screening as they go through airports. Other measures, such as iris scanning, could also be used.
In the United States, there is a similar scheme for approved frequent travellers, who have fewer security checks such as not having to remove laptops from bags or take off shoes.
