Deputy Prime Minister Winston Peters said today he was pleased the army was now running the quarantine and isolation process - up until now it has been the Ministry of Health.
Peters told Newstalk ZB's Mike Hosking that the army knew how to introduce and follow protocols and instil discipline.
He did not want to specifically point the finger of blame directly at Director General of Health Ashley Bloomfield for the border bungles.
"It stops with the people who have the protocol in their control... at the place where it had to be exercised, and they didn't do their job. That's where the buck stops, and with anyone who knew they weren't doing their job.
"It's not good enough...some people are letting us down," Mr Peters said.
He takes a differing view with the Prime Minister, Jacinda Ardern, when it comes to what should be done to those responsible for the blunder.
Mr Peters told the House that the Government would find those people "at the coalface who didn't follow the protocols".
"The only way we can eliminate this sort of irresponsible behaviour or failure to fulfil the protocol requirements is to identify those people and make sure it doesn't happen again."
