NZ First leader Winston Peters has expelled Brendan Horan from the party after receiving "substantive material" that caused him to lose confidence in the MP.
Mr Peters said Mr Horan had a duty to resign as an MP.
"This is a bitterly regrettable situation but we had to place our decision on the public record as soon as we were in a position to make it. The nature of this inquiry means I am unable to make any further comment outside Parliament."
He sought leave to make a personal explanation and said allegations had been made against MP Brendan Horan relating to a family matter."The allegations were of a nature that they should be treated seriously."
Mr Peters told Parliament: "Substantive infromation has come into my posession some as recently as 2.15 this afternoon. The information we have received leaves me in a position where I have no confidence in Mr Horan's ability to continue as a member of Parliament and he will be expelled from the NZ First caucus forthwith."
Speaker Lockwood Smith interrupted Peters to point out his personal explanation should relate to him not another member.
Peters said he was required to conduct a full inquiry into the matters relating to Horan and he wanted to report the results of that to the House.
