Chris Hipkins says he still has confidence in Cabinet Minister Kiri Allan.

The Prime Minister has confirmed he'll be having a "good chat" with Allan after he returns from Europe next week, following allegations about historic tensions in her office.

Allan has been on mental health leave, and is now on leave for school holidays.

Hipkins told Tim Dower everyone makes mistakes, and Allan is no exception.

Meanwhile, Hipkins is still piecing together how Labour MP Ingrid Leary ended up in a Mongrel Mob election hui, mistaking it for an Electoral Commission meeting.

He says if he was her, he would have left the meeting as soon as he'd discovered the mistake.
