Career
He is a published author and a former General Superintendent of the New Zealand Assembly of God. He is currently pastoring in Brisbane. Williams received his training at a Bible College in Tauranga.
In 1979 Williams followed Frank Houston as General Superintendent of the New Zealand AoG. He proved a dynamic leader, gaining popularity as a speaker with his regular programme on the newly formed Radio Rhema.
The denomination as a whole was experiencing new growth:
Williams became a published author with a work based on the book of Proverbs called Wisdom - the missing link a book on handling pastoral problems. One of the most difficult things he had to manage as General Superintendent was the fallout following the revelation of the financial and moral failure of Neville Johnson then pastor of the largest church in Australasia, the Queen Street Assembly of God.
Williams left for Australia in March 1989, the leadership of the AoG then passing to Pastor Wayne Hughes. In Australia Williams served in what was then known as the Garden City Church in Brisbane.
In 1994 the Executive of the New Zealand AoG received a letter from the Australian Assemblies stating that Williams had been guilty of adultery while pastor at the Hamilton Assembly.
Williams was replaced as Pastor of the Garden City Christian Church by his deputy Senior Pastor, Pastor Geoff Holdway. Ps Holdway differed from Williams charismatic style by focusing on a more fundamental adherence and teaching of scripture. At this time Williams was pastoring in Australia.
He lost his Australian credentials, but these were eventually returned after a time of counseling.
However he remained barred from ministry in the New Zealand AoG due to a failure to make any efforts to put the matter right in New Zealand. In 2000 it became apparent that the extent of his sexual impropriety was much greater than admitted to the Australian body.
His credentials in New Zealand were permanently revoked for adulterous offences and other indiscretions involving different women over an extended period of years. Following this the Hamilton Assembly (Gateway Christian Centre) left the denomination.
