A group of volunteers in Tasmania's north is saving the fruit from suburban backyard trees from going to waste.

The Meander Valley Harvest Helpers pick the produce for those who are unable to, and give it back to the community.

Harvest Helpers volunteer Wendy Kilroy said it was for a good cause.

"We come and harvest, and then the produce is sorted and turned into other preserves or sauces and given freshly to those who need it," she said.

"Doing this service certainly helps everyone: the grower, as well as the receiver, and as well as ourselves, getting out in the fresh air and enjoying life."

Harvest Helpers volunteer coordinator Nan Preston said the fruit was divided between the tree owner, the volunteers and anyone else who needed it.

"A lot of people that are in need, they're either homeless or close to homeless, or their money isn't lasting to the next pay day," she said.

The group did 12 picks last year, and this season their workload has doubled.

"Eventually we need to prioritise who we can go and pick for and the first of course would be the elderly and people who are unable to go out and pick their own fruit so that it's not wasted," she said.

"That's my passion — food security for everyone and the ability for people, regardless of their situation, to be able to come in and get clean food."

Some of the fruit is distributed fresh, while the rest is preserved and made into purees and sauces.

Volunteer Tomoko Woods said the group was passionate about preventing food waste.

"I don't waste any food at home," she said.

"I don't want anyone to waste the food so that's a good thing to promote."

The Harvest Helpers picked more than 400 kilograms of fruit from Tanya Cavanagh's fruit trees in Meander.

Mrs Cavanagh said if it had not been for the volunteers, much of the fruit would not have been picked.

"We would've done our best, but pretty much a lot of it would've gone to waste," she said.

"I really liked the idea that one, they help, but two, it goes out to people that need it."
