Prime Minister Scott Morrison has pointed to the resignation of Gladys Berejiklian as a reason not to introduce a NSW-style federal corruption commission.

The NSW Independent Commission Against Corruption is investigating the outgoing NSW premier for potential breaches of public trust linked to her secret five-year relationship with former Liberal MP Daryl Maguire.

The resignation of the popular premier on Friday renewed calls by federal Labor, the Greens and independents for a national corruption body.

But Mr Morrison thinks this is a reason not to have a NSW-style ICAC.

“It’s certainly not a model that we’d ever consider at a federal level and I think that’s been on display for some time,” Mr Morrison told Seven Network on Tuesday.

“You’ve got to have processes that assume people are innocent before they sought to be guilty.

“I’m sure there are millions of people who are seeing what’s happened to Gladys Berejiklian and understand that’s a pretty good call not to follow that model.”

The Coalition government has said it is committed to introducing laws to parliament this year for a national integrity commission, after working through submissions and consultations.
