The church took possession of the impressive parish and community hall, next to St John's Presbyterian Church, on schedule on November 8, after 100 building days.
Five to 20 contractors had been on site at any one time and worked harder to make up for lost time due to extreme winter frost, Arrow International project manager Hayley Tribble said.
The hall is virtually finished.
With the use of movable wall panels, up to three groups will be able to use the facility at the same time.
Alternatively, the entire facility can be opened into one area. Skylights in the ceiling are remote controlled and close automatically if rain starts to fall.
There was 3km of piping for the underfloor air-to-water heating system.
Male, female and disabled toilets were fully serviced and the large kitchen and servery were being equipped.
A secure cupboard awaited audio and visual equipment.
The Arrowtown School choir and Mainly Music parents, caregivers and children are expected to perform at the first service.
"As one of our elderly members of the congregation said, it's so nice to have something new," St John's Church building committee chairman Bruce Patton said last week.
"We've made do with second-hand for years and the old church hall was third-hand."
The project cost $1.3 million, including construction, restoration of the church, professional fees, the resource consent process, and development contributions to the Queenstown Lakes District Council.
It also covered the relocation of the former church hall, originally the Miller's Flat Church, to a new site behind the historic miners' cottages.
Restoration of the exterior of the church was also coming to an end, with new weatherboards installed, the chimney repaired and painting to be completed.
Interior renovations of the church would fully begin and end next year, when parishioners and user groups could transfer to the new hall.
The historic church bell would be mounted in a cradle on a concrete pad in the area to be landscaped in front of the hall.
Mr Patton said the parish needed another $150,000 in donations and grants to pay for the hall, its furnishings and audio equipment, plus refurbishment of the church.
