Palmerston North artists Gemma Farrell and Mikal Carter have just about finished work to their over 30 metre long mural in the Ucol car park. The mural is a "gift to the public", from Good Earth Matters.

What was once a bland car park wall is now home a masterpiece representing Manawatu's connection to nature.

Palmerston North's latest artistic addition is courtesy of Good Earth Matters and can be seen on a carpark wall next to UCOL on King St.

Artist Gemma Farrell said the work was commissioned by Good Earth Matters, with the help of the Palmerston North City Council, to celebrate its 20th anniversary and as a gift to the community.

Farrell, who works with Placemaking Palmerston North, said she was "stoked" with how well it had gone.

"It's so close to being finished now. It's quite amazing, because you're looking at it as a concept."

Working alongside Mikal Carter since late April, the piece spans an area of 33 metres by 5m, and was the biggest she had ever painted.

Using spray paint and brushes, the work includes wildlife and the Manawatu River, which flows from a Mother Earth figure's dress, she said.

Good Earth Matters wanted to celebrate its 20 years of environmental and resource management work in Manawatu with a "gift to the public".
