The St John's congregation will gather on Sunday to worship across the road from where they once met.
Reverend Ed Masters said given the love and support they had received since the church was destroyed by fire on Wednesday, he expected more people than normal may join them at the combined service.
It will take place on the grassy area across from the church, on the corner of Ranolf and Victoria Sts, at 10am.
The joint police and fire investigation to determine the cause of the fire is continuing, police say.
Detective Sergeant George Staunton said more calls with information had been received and that was being worked through.
