A group of Dunedin children are shunning free time these school holidays and bringing a bit of colour to their neighbourhood.
Greater Green Island Community Network worker Amanda Reid said there was previously a mural from Keep Dunedin Beautiful there, but over time the anti-tagging coating had worn.
Last year especially it became covered in graffiti, she said.
About 20 young volunteers have this week been painting the Runciman St pedestrian tunnel linking Green Island with Abbotsford.
The network organised a local painter to waterblast the walls and people doing community work helped prepare them for painting.
Dunedin artist Jonathan Waters worked with intermediate school pupils to design the mural, she said.
"Every young person has designed what goes in their letter."
The brightly illustrated words "Abbotsford" and "Green Island" line the respective sides of the wall.
Another smaller section of the tunnel will be painted by Waters and other artists.
Today is the last of three painting days and the network hopes to have an official unveiling on October 18.
