The Wikipedia page on the Samoan Assemblies of God in New Zealand has a section on head covering. I cannot find the information anywhere else.
I'll paste it below, but first an extremely quick summary:
- women are allowed to be pastors and preach in their churches - in fact the any woman in ministry *must* wear a covering, while others are merely encouraged to.
- the church's position is that it culturally shows respect for God and is a "reflection of royalty" because "women in ministry recognize themselves to be Daughters of the King."
The explanations are not from the Bible, but the application (prophesying) gives a nod to 1 Cor 11:5.
It's long been my contention that the Early Church (and later periods) mixed cultural understandings of head covering with biblical teaching. This is a contemporary example.
Here is the section:
Head Covering for Women: Women in ministry wear head coverings or hats to church. When serving in the worship team to preaching and prophesying, it is a requirement for women in ministry. Culturally, it is an act of reverence that Samoan women in general have towards God, therefore this is not only a requirement in this movement, but across every other Samoan church. For other women in the church, it is encouraged but not enforced. This aspect is a reflection of royalty in the movement, as the women in ministry recognize themselves to be Daughters of the King.
