The prime minister has dismissed suggestions a federal integrity commission would operate with the same open justice process as courts.
"It's not a court," Scott Morrison told reporters while campaigning in Darwin on Tuesday.
Mr Morrison opposes the way the NSW Independent Commission Against Corruption operates, labelling it a "kangaroo court" that could do irreparable damage to an innocent person's reputation.
He doubled down on his criticisms when pushed on whether open justice was a key pillar for a federal anti-corruption commission.
"Where matters were to proceed under our model that involved criminal behaviour, they would go to court and that's where that process would be followed," he said.
"That's how we've designed it. That's consistent with how the justice system works."
Mr Morrison earlier visited a display home in Palmerston City, just outside Darwin, spruiking his new housing policy which would let first home buyers dip into their superannuation accounts to help fund a deposit.
The coalition is confident of picking up the NT seat of Lingiari, following the retirement of long-serving Labor MP Warren Snowdon.
The prime minister also weighed into the law and order issue, which has been subject to fierce debate in the territory.
A re-elected coalition would support local communities to address crime rates but ultimately it was the responsibility of the Northern Territory government, he said.
"We really need the Territory government to get on top of the law and order issues here in the territory, that's their job," Mr Morrison told Darwin radio 104.9 on Tuesday.
"We've been certainly stumping up to work both on the preventative and supportive - positive measures you can do but as well as on the law enforcement side with patrols."
