Prime Minister Jacinda Ardern defends Government despite recent controversies

The Prime Minister is defending her government despite having to stand down two ministers in as many weeks.

Yesterday it was announced Meka Whaitiri has been stood aside pending a 'staffing' investigation.

Newshub understands she is accused of 'shoving' a press secretary who'd only been in the job for two weeks.

"I need to allow natural justice to apply here - so I won't be making any comment until that is completed," Prime Minister Jacinda Ardern says. 

But National leader Simon Bridges says the Prime Minister should act now.

"Tell you what I would do. Get them in, to know exactly what happened - and if there is violence, the minister would be gone." 

Aside from the allegation of violence - Newshub understands there's been a high turnover of staff in her office.

The Ikaroa-Rawhiti MP usually has a roster of six ministerial staff - and at least five have gone in the past ten months.

This incident comes just a week after Minister Clare Curran was sacked from cabinet for having an undisclosed meeting

"I think it tops off an incompetent, shambolic few days for the Prime Minister - she needs to step up and take a lead on these issues," Mr Bridges says.

Despite the double-demotion - Ms Ardern says she still has confidence in her Ministers.

"Regardless of any incident - at any time - my expectations are high."

The Prime Minister will make a final decision on Ms Whaitiri once the investigation's complete.

And after accusations she was 'soft' on Clare Curran - she's facing pressure from the Opposition to resolve this latest problem, quickly.
