IceInLine Alexandra is looking for public support to complete the final stage of its five-year redevelopment plan.
Committee spokesman Trevor Lawrence said while funding was secure for the roof, which was under construction, the club wanted to raise a further $200,000 to complete the upgrade.
The roof was expected to be completed in March and the committee planned to make the existing lounge area into a function centre as well as replace some worn-out items and signage.
They were offering people the chance to buy a piece of the rink to fund that project.
There were 1800 square metres of ice and it would all be on offer to $100 a square metre, he said.
Each ice owner would be recorded on a board at IceInLine. Families could get together and buy a square, while businesses might be keen to purchase a few.
Every ice purchase and donation was vitally important and would be recognised, Mr Lawrence said.
"Not just the largest ones — small ones are important to us. It’s not a competition about who can give more."
Funding from Central Lakes Trust, Otago Community Trust, NZ Lotteries and the Central Otago District Council was paying for the $1.4 million roof, which followed on from the installation of a new refrigeration plant — which heated the neighbouring Molyneux Aquatic Centre — and new curling facilities.
Footings for the roof had been poured and approved by the Central Otago District Council. Materials had been ordered for the next stage, he said.
"The roof is fabulous, the curling rink is fabulous but the rest is a little tired."
The next stage was to replace matting, lighting, ice hockey nets and dasher boards around the rink and finish it all off with landscaping.
Nearly 30 years ago IceInLine appealed to the community to buy sheets of gib board and literally put it up. Times had changed since then but buying an ice square was a way for the community still to be involved in the project, including people from out of town, he said.
