"It will also provide the opportunity for local Hawke's Bay up-and-coming mural artists to be part of the festival."
As well as New Zealand artists there will be artists arriving from the USA, Brazil, Portugal, France, Germany and Australia.
As a build-up to the artworks event there will be a series of free guided walks for locals and visitors to see the existing murals - as part of Seaweek 2017 which kicks off on February 26 and runs through until March 5.
"Everyone knows something interesting about Antarctica or the Amazon River, but closer to home the natural world can be a mystery," National Aquarium of New Zealand educator Jake Brookie said.
He and Mr Merken have teamed up with to lead the walks to view the murals in Napier's CBD and Ahuriri, focusing on how they have been made and what they depict.
Mr Merken said the Sea Walls: Artists for Oceans events helped raise public awareness about "critical ocean issues" as well as beautifying the city landscape and creating a "real sense of pride and ownership of public spaces by the local community and visitors".
The founder and director of the Hawaii-based non-profit foundation, Tre' Packard said he was looking forward to returning to Napier to again lead the project and support the artists.
"By taking the oceans to the streets we aim to inspire communities to be aware of and and be proactive about what is happening to our oceans."
He described New Zealand as "a special place" with a unique marine environment which deserved protection.
"We look forward to enriching Napier's landscape with more murals."
As part of this year's mural event an artist's panel discussion will be held at the MTG Hawke's Bay on March 25.
