Labour MPs had a secret Zoom meeting last night without disgruntled MP Dr Gaurav Sharma to discuss his fate.

The NZ Herald understands MPs met at 8pm, but Sharma was not told of the meeting.

He found out about it after a message - including a photo of Kelvin Davis on the zoom call - was sent to him by mistake.

"Apparently caucus had a full meeting at 8pm yesterday with all members except me and the decision was predetermined," Sharma said in a text message sent to NZME.

It comes as Labour's caucus meets at 2.30pm, as announced by Prime Minister Jacinda Ardern yesterday in her post-Cabinet press conference.

Ardern did not mention any plans for a meeting set for last night.

Sharma today told the Herald he was unsure whether he would make today's afternoon meeting, given he had other engagements.

However, he expressed his desire to have a "fair trial".

Ardern is expected to front media about 4pm.
