The police union says it will be impossible to manage the Auckland's Covid boundary over summer.
Prime Minister Jacinda Ardern has said a hard perimeter is staying, and Aucklanders will have to show proof of vaccination to leave.
On Wednesday on Checkpoint Covid Minister Chris Hipkins suggested holidaymakers could be given time slots to drive out of Auckland - one option under consideration.
On Thursday morning on RNZ's First Up, Deputy Prime Minister Grant Robertson walked that suggestion back.
But on Thursday afternoon Hipkins released a statement saying, "no system will be perfect," and it would be challenging but the government is working on options for the border over the holiday period.
Auckland Chamber of Commerce CEO Michael Barnett told Checkpoint if Auckland’s overall vaccination rate is over 90 percent double dose by the Christmas holidays then Aucklanders should be free to travel across the border without checks.
“Police are not travel agents and I don't believe that they would be able to manage,” he said.
“I can't see any other system that they can put in place between now and the beginning of the Christmas holiday period.
“If you tried stopping those vehicles, you'd have a backup from Pokeno back to Auckland, and the same thing the other way. I don't believe it's workable.”
