The Human Rights Commission has received 16 complaints about Brian Tamaki's rant blaming gay people for earthquakes.
In a sermon the day before last week's massive 7.8 magnitude earthquake which killed two people, Tamaki told churchgoers quakes were a result of sexual perversions.
He also blamed a gay priest and the people of Christchurch for the devastating earthquakes that hit Canterbury in 2010 and 2011, killing 185 people.
A spokeswoman for the commission said 16 complaints had been received about his speech, which could result in mediation.
After the rant was reported by the Herald, Human Rights Commissioner Richard Tankersley branded it as "disgusting."
