The $100,000 campaign has been funded by Development West Coast and includes television advertising, outdoor billboards in Christchurch and Wellington, and a website upgrade.
DWC chief executive John Chang said the campaign was positive news for the region.
"The campaign will show how much Coasters enjoy our water and what fun and enjoyment we get from it."
Like other regions in the South Island the global economic downturn and Christchurch earthquake had affected visitor numbers to the Coast. When coupled with the Pike disaster, he said it was a good time to embark on a campaign like this.
"While there have been recent setbacks, we wanted to show our confidence in the Coast and the strength of its economy. This tourism initiative will remind the rest of the country we are still open for business and how wonderful and dynamic the West Coast is," Dr Chang said.
The four-week campaign begins on TV One on October 18. Viewers will then be directed to the website www.visitwestcoast.co.nz.
