The trust, chaired by Jane Peeti, has offices in Whanganui's Ridgway St Community House.
They were blessed on December 19.
Other trust members are Aroha Rozska and Billie Mills. Uru Gardiner, Carol Rameka and Anahera Haami are the trust's pou kuia (supporting elders).
The trust is likely to seek the usual funding pathway - through government, Kairimu-Davis said. But it's a kaupapa Māori group.
"My kōrero to the people out there is that the funding will come from the sky, which is Ranginui, and our houses will come from Tane Mahuta, which is the forest, and the foundation of all of us is Papatuanuku," she said.
Police have told her a men's shelter is a brilliant idea, and the group will introduce itself to Whanganui Women's Refuge and may work with it.
Kairimu-Davis will be the unpaid manager, and said people can ring the trust's office on 06 281 3158 or 020 4003 0246.
