"When I looked it at I thought, 'that looks pretty cool', but it wasn't until I brought it inside that I turned it around and thought, 'wow'."
The stay-at-home mum said once she stood the feijoa down on her kitchen table, she realised it looked like the feet of a kiwi.
"It's tiny, the body is about the size of a grape ... Our feijoas this year are the biggest I've ever seen so it's quite funny to find such a little fruit like that."
Lukis, who was "buzzing out", showed the feijoa to her four kids.
"My two big boys thought it was real neat, they said I needed to take a photo."
Members of the Beach Haven community page on Facebook suggested Lukis put the little kiwi on Trade Me, she said.
"I think putting it up then donating to charity is a really awesome idea ... I'm not sure whether to freeze it, and whether anyone would want to buy it, but it's a special find.
"I'd like to put the money towards suicide awareness."
She said she was open to any tips on how to preserve the tiny feijoa.
