The Anglican Church has agreed to look at ways same-sex relationships can be part of church life, but will not marry gay couples.
The church's General Synod, held at Waitangi this week, has decided to uphold the "traditional doctrine of marriage" but work towards ways to recognise committed same sex relationships.
In a statement, the church said the Synod recognised the pain to the LGTB community, and apologised unreservedly for the times the church had contributed to that pain.
A working party will now be appointed to look at options for same gender blessings, while mindful gay marriage is still unlawful in some Pacific countries.
The party will report back in 2016, but any changes would take at least four years.
