1News revealed Ilam MP Hamish Campbell's association with the church, which has no official name but has been called the ‘Two By Twos’ and ‘The Truth’.
Campbell told 1News he was aware of the historical allegations, but had no personal knowledge of the individuals involved.
The church is estimated to have about 2500 members in New Zealand and thousands overseas.
The church is currently being probed in New Zealand, Australia, and the United States over the abuse allegations.
Campbell told 1News the church is “a non-denominational Christian group just trying to live the best way possible”.
“I have an association through my family. I’ve also been a scientist for the last 20 years, so I have quite a broad view socially liberal," he told 1News.
Police recently contacted current and former members about alleged sexual offending, and Campbell said this was the best place to deal with any concerns.
In a statement to the New Zealand Herald last night, Campbell said allegations of sexual abuse, or any other serious misconduct, must be thoroughly investigated and addressed with full accountability.
"My connection to the organisation has been through family, and while I have been made aware of these historical allegations through the media, I have no personal knowledge of the individuals involved," he said.
"My wife and I are non-denomination Christians, but my faith is separate from my role as a politician and I consider myself a social liberal. My views are shaped not only from my upbringing, but also my scientific career."
