Other anti-abortion groups have included Family Life International, Family First New Zealand, the youth-based organisation ProLife NZ, Focus on the Family New Zealand. Some of these anti-abortion groups had international connections and also took an interest in other issues including euthanasia and in vitro fertilisation. These anti-abortion groups were often well-funded. According to McCulloch, Right to Life had an annual income of NZ$25,000 to NZ$35,000 a year during the mid–to–late 2000s; spending NZ$80,000 on its legal challenge against the Abortion Supervisory Committee by May 2009. Some former anti-abortion groups have included Operation Rescue New Zealand, Women for Life, and the Kiwi Party. In 2013, McCulloch has estimated that the anti-abortion movement in New Zealand had tens of thousands of members.
