A new roof, walls, exterior cladding and nearly completed upgrades to toilets have been funded by supporters of the club and money earned through fundraising efforts.
Club president Avis Ward said the plan was just to upgrade the toilets three years ago, but extended to the rest of the club after encouragement from the members.
"We decided a few years back to renovate the toilets but ... we’ve had new members come in — and [they] instigated ... we do quite major renovations," Mrs Ward said.
The club celebrated their centennial in 2009.
Renovations started this year with work done by a mix of club members, volunteers and local businesses.
Auckland company Colorcote donated the roofing coil which Invercargill Roofing Industries "ran through their machines to create the form of the roof".
Club member Brent ‘Stearnie’ Stearne said he was humbled by the donation of the materials and work done by both companies.
"It was quite amazing of them to do this for us," Mr Stearne said.
Hiring out the club, providing catering and running regular bowling tournaments enabled the outfit to pay for "$60,000 worth" of renovations.
Club secretary Jenny Pulley said she was very proud of what they had achieved.
"If the other groups had not have come on board we couldn’t have come this far," Mrs Pulley said.
The club received funding from the Aotea Gaming Trust.
Shelter sheds placed around the bowling green were donated by life member Jimmy Fowler.
Mrs Ward believed the club had been the backbone of the Winton community and the renovation efforts had drawn more people to it.
"The club has meant so much to the community, it’s a nice, friendly atmosphere.
"After the renovations are done, we just want to keep growing the club and create the next generation of members."
Work on the bowling green and the gardens was expected to be finished in the following months.
An informal function was planned to celebrate the completion of the renovations.
