"It's different - but, if anything, I think I'm bringing in more colour and vibrancy.
"There is a real artsy vibe in Eketahuna, so I think it will fit."
Watson arrived in Eketahuna last year, after having searched "all over the lower North Island" for a gallery space.
"It was on my bucket list to start a gallery," he said.
"I knew I wouldn't be happy doing anything else but art - so a gallery was the next logical step."
Eventually, he "fell in love" with the church, buying it from the Living Springs Christian Centre, and spending the past six months renovating the inside.
The church was built in 1908 and had an initially flourishing community.
It fell into decline during World War I, with no services held and the building becoming a haven for squatters.
After being briefly used as a school, it was refurbished in the 1930s, and boasted an active congregation during and after World War II.
Membership decreased in the 1970s with the union of the Methodist and Presbyterian churches, and it was eventually used as a youth centre by Living Springs - who left the building vacant two years ago.
"There were old bibles and birth records everywhere - so I learned a lot about the people born here.
"Plus, the timber work is amazing."
Watson has been painting from a young age, and studied art at the Western Institute of Technology in New Plymouth, later exhibiting in Palmerston North and Mangaweka.
As a keen skateboarder, his art is heavily influenced by 1980s skateboard graphics.
He also draws inspiration from Impressionism and Cubism.
"I just throw as much colour at it as possible, and I make an image from there - the paint tells you where it wants to go.
-Rev's official opening will be held Saturday, March 7, from 5pm to 7pm.
