More than 1 million people travel in each direction across the Tasman annually and holdups at the border are a source of irritation for those who travel frequently.
Wagner said it wasn't known how many passengers would be needed for the $1.6 million trial, but it would require a sufficient number to identify any problems with it.
It was not known whether police checks would be needed, but authorities would also work with the organisations passengers work for.
The trial has been welcomed by Flight Centre.
"Should the trial be a success, anything that ensures customer experience is as best it can be by streamlining the processes at our border is going to be a positive," said NZ managing director David Coombes,
The Government will also spend $2.8 million over two years to speed up clearance of low-risk goods across the border.
