Inside New Zealand: How to Spot a CultCult-like groups are on the rise in New Zealand. Now the two-part Inside New Zealand: How To Spot A Cult documentary uncovers what really goes on inside these often controversial groups.

Inside New Zealand: How To Spot A Cult gives viewers an intimate view of what life is like inside groups that some former followers say are cults operating in New Zealand.

These former members have consistent stories about how the different organizations actually work, explains producer Gary Scott, and the techniques they say were used to control them, even though the belief systems can be miles apart.

The modern rise of cult-like groups is not something experts can easily quantify, but there is a proven trend away from mainstream churches, towards other forms of spirituality. There has been a lot of talk about Destiny Church, since the covenant of 700 followers.

The two-part documentary consists of ex-believers' stories, and investigates the similarities they say exist between groups including the Exclusive Brethren, Scientology, Centrepoint, Gloriavale, Avatar and the International Church of Christ.
