The most recent MP to come out as gay said he was prompted by homophobic comments from Destiny Church's Bishop Brian Tamaki.

National list MP Paul Foster-Bell came out in a Q and A interview on tv, saying Mr Tamaki's assertion that gay people caused the Kaikoura earthquake could be harmful to younger LGBT people.

He said Bishop Tamaki's comment, along with what he said is the rise of a homophobic administration in the US, means he had a moral obligation to come out.

Mr Foster-Bell denied the idea he's coming out to gain support before next year's election.

He joins his own party's MP Christopher Finlayson, and three opposition MPs in being openly gay.

Mr Foster-Bell's comments come as the gay community rally's to protest against Bishop Brian Tamaki.

A group has been outside Destiny Church in Manukau today participating in a protest disco.

Tonight in Wellington an event called Gay Quake is being held at music venue San Fran.

Organiser Nicole Skews-Poole said it's ridiculous that Mr Tamaki suggests gay people caused the 7.8 magnitude quake.

"Any queer community response should have some kind of fundraising element to it so that we can give back to the people that have been affected by these earthquakes, as well as taking a stance that it's a bit ridiculous so lets sort of have a bit of a protest party" she said.
