Resene approached the organisers of Goldfest in Waihi with the idea of involving the rainbow in the Goldfest celebrations with an actual pot of gold at the end of the rainbow.
Resene managing director Nick Nightingale said the company had supported towns in New Zealand with fundraisers and support of local schools and community projects.
"And what better way to celebrate colour and Waihi, than with a rainbow of colour with a pot of gold at the end?"
Goldfest would run through October in and around Waihi with events and activities for all ages.
The rainbow was on its way to Waihi today, no doubt attracting attention along the route down.
GO Waihi Coordinator Brian Gentil said he was hopeful the rainbow would be in place at Victoria Park on SH2 by mid October.
