Prime Minister Jacinda Ardern has sacked Iain Lees-Galloway as a minister.
She fronted a press conference on Wednesday, where she made the announcement.
It comes after National leader Judith Collins claimed to have passed a "tip-off" about a Labour minister onto the Prime Minister.
12pm - That ends our live updates for Wednesday morning.
11:55am - Lees-Galloway no longer appears in the Labour Party website's "Our Team" section, which lists MPs. Despite having previously announced their resignations, the likes of Ruth Dyson and Raymond Huo remain on the list.
11:40am - If you missed Ardern's press conference, where she confirmed she had sacked Lees-Galloway, catch up here:
11:30am - Lees-Galloway no longer has a profile on the Beehive website's list of ministers.
11:20am - Ardern left it up to Lees-Galloway to decide whether to run again for Parliament. He has decided not to.
In regards to whether Collins mentioning the claims on television was appropriate, Ardern said each leader had their own way of dealing with information.
She said "there are clear differences" in how Collins dealt with this information in comparison to how Ardern's office dealt with an email about Andrew Falloon.
"Once I received information, I passed it directly onto the Leader of the Opposition and I discussed it no more widely than that," Ardern said.
She says regardless of the circumstances under which she became aware of the information, her actions would have been the same.
Ardern said there is an expectation in her caucus about what is acceptable.
She hopes recent political scandals don't affect voter turnout at the September election.
11:15am - Here is a statement from Iain Lees-Galloway:
"I accept the Prime Minister’s decision and apologise absolutely," Lees-Galloway says.
"I have acted completely inappropriately in my position and can not continue as a Minister.
"I have apologised to my family for letting them down. Please appreciate their privacy.
"I also apologise to anyone who has been hurt by my actions."
11:10am - Carmel Sepuloni becomes ACC Minister, Andrew Little becomes Workplace Relations and Safety Minister and Kris Faafoi becomes Immigration Minister.
Ardern says she has taken into account a range of circumstances, including that he was the Minister of Workplace Relations and Safety.
"In undertaking this relationship, he has opened himself up to accusations of improperly using his office.
"He has not modelled the behaviour I expect as a Minister that is in charge of setting a standard and culture in work places."
Ardern wasn't previously aware of rumours about Lees-Galloway, she says.
The former minister showed a "signifcant lack of judgement".
She is not familiar with the individual who has raised the allegations. The tip made a "range of allegations".
11:05am - Confirmed: Jacinda Ardern has dismissed Lees-Galloway as minister.
On Tuesday afternoon, a third party alleged that the minister had an inappropriate relationship with a former staffer from one of his agencies.
Later in the evening, Ardern questioned the minister. He confirmed the consensual relationship, which lasted a year. The relationship ceased several months ago.
The Prime Minister is wanting to protect the individual's identity, so won't be releasing detail about their role.
During the pair's conversation, Ardern advised Lees-Galloway, the Minister of Workplace Relations and Safety, that he would not continue as minister. She said he showed a "lack of judgement".
He accepted her decision and decided that he won't stand at the next election. He represents Palmerston North.
