Connecting Communities Wairarapa painted the town in a see-through varnish on Sunday leaving surprise art works that would be revealed on the next rainy day.
Manager Sandy Ryan said she had seen a YouTube video of a man doing "rain art" in Seattle so decided to bring the craft to the streets of Masterton.
Mrs Ryan designed and then made 13 large stencils that had different phrases relating to rainy days, like "jump in puddles" and "I love falling asleep to the rain".
When the stencils, which range from around two to five metres long, are sprayed with a waterproof super hydrophobic sealer, the sprayed area will go on to deflect water.
"So when it rains you will be able to see the artwork. I think we're the first to do it here in New Zealand, no one else seems to know about it," said Mrs Ryan.
