Dr Gaurav Sharma is still hoping for an independent investigation.

The MP for Hamilton East was expelled from Labour's caucus at a meeting on Tuesday morning.

Prime Minister Jacinda Ardern said as far as Labour's caucus is concerned, the Sharma saga is over.

Sharma will now sit in Parliament as an independent MP. He is still a member of the wider Labour Party, although it is now very likely he will be expelled from that too.

He told Heather du Plessis-Allan he's going strong and this is about getting fair treatment.

"The message this sends is that if your boss is powerful enough, they can get away with anything and it’s the wrong message to send from parliament to all the New Zealanders out there.”
