The shop provides emergency assistance in the form of clothing, furniture and, when available, food to disadvantaged members of the Rangitikei community, she says.
"We encourage volunteering and providing a location where young people can get work experience."
However, the group was forced to change its name, as they couldn't use the name Koha Shed.
"We didn't understand at first but it was made clear that we had to do our own thing - and we now have," Ms Harvey-Larsen said.
The cosy, colourful little shop behind a church is inviting and not only can people go in, get what they need and have a chat, their situation is very important to the group.
"We do really care, so we try to operate as a foodbank as well as much as we can."
Every Thursday is hot lunch day and everyone is welcome to pop in and get some hotsoup or whatever else happens to be on the go.
"We get a lot of older people coming with their thermos and filling up for two days. We're also thinking of cooking a lasagne or macaroni cheese in a crock pot."
Ms Harvey-Larsen said there were many people looking for help Marton who didn't have much money.
"I saw the gap in our community when I came back from Whanganui flood."
The beauty of getting known well throughout the town has meant that even people outside town are now being helped by the group.
"We helped an old man who was very ill and taken to Palmerston North Hospital from a remote place outside Dannevirke.
"We were asked by a local pastor to set up a small flat for him in Palmerston North, and we did. We furnished it completely and I know we made that dear old chap very comfortable."
She said the group was about kindness and understanding.
"And a little of both goes a very long way."
