Bargain hunters and treasure seekers have one last chance to find hidden gems at Wastebusters Alexandra site.

The social enterprise announced in April its Boundary Rd operation was not financially viable and it would permanently shut the doors on June 30.

The closure comes 23 years after Central Otago Wastebusters was formed.

The organisation has stopped taking in new donations of pre-loved goods and, in preparation for its closure next week, is having a Koha Day on Saturday.

The day is an opportunity for the not-for-profit community enterprise to give back to the Central Otago community one last time.

All proceeds from the day will go to the Otago Southland Rescue Helicopter Trust, St John Alexandra and Puna Rangatahi, which supports youth across Alexandra and the Teviot Valley.

Communications coordinator Alexia Johnston said the aim was to ensure all funds remained in the community for the people of Central Otago.

“It’s going to be a great day. Not only will every cent go back to some fantastic charities, people who purchase treasures on the day will be taking home a piece of history.

“There will be plenty to look forward to, aside from the usual treasure hunting. We’re aiming for a party atmosphere, with cake at 11am, and a coffee van on site. Remember to bring your reusable cup or you can use one of ours.”

Site manager Brendan Smith said the day was also about celebrating the work Wastebusters had done in the community over the past 23 years.

“We’re inviting everyone who loves Wastebusters, who has been part of our story, to come along and have some cake at 11am,” he said.

“Koha Day is about bringing the community together to help us celebrate what we have achieved over the two decades and giving Wastebusters Alexandra the send off it deserves.”

Gates will be open 9am to 5pm.
