Thirty of the world's best street artists have been unleashing their talent on some of Napier's biggest walls.
The artists call it 'artivism' - activisim through art - and the result is powerful and provocative.
The global street art project is transforming many of the city's unused walls into extraordinary works of art.
Each of the artists has been assigned a wall in the CBD to paint a mural in their own style using the marine life theme to raise awareness about the plight of the ocean.
Sea Walls festivals have already featured in in Los Angeles, Vietnam, Mexico and Sri Lanka.
The visual story telling aims to bring what's happening in our oceans and around the world into the public eye in a relatable art form.
And by incorporating local people into the mural the artists hope to give them a sense of ownership.
The stunning imagery includes a giant octupus entangling itself with an equally enormous sea eel on the wall of our national aquarrium.
Canadian street artist Jason Botkin told Seven Sharp he wants it to be "playful, bright, colourful and fun" while engaging "a very broad audience and demographic".
