Napier City Council has released more information on the re-design of the National Aquarium on Marine Parade, saying Wellington's Weta Workshop will be brought in.
Mayor Bill Dalton said the new design will bring in more visitors, grow the local economy and generate jobs, as well as making a contribution to marine science research, education and conservation.
Council chief executive Wayne Jack said they are pleased to have Weta on board.
"We couldn't be more thrilled that Weta Workshop has come on board as our design partner, to create the wow factor and help us tell our stories in an innovative, original way," Mr Jack said.
"Weta's commitment, as well as the support of our other major partners, means that this project has the potential to really fly."
Sir Richard Taylor of Weta workshop said they too were looking forward to developing ideas.
"It's terrific to have the opportunity to work with the team from NCC and the National Aquarium of New Zealand on this project and we look forward to kicking off the concept design phase," Sir Richard said.
"We are excited by the prospect of finding new and unique creative experiences that connect visitors emotionally with the conservation challenges faced by our oceans and natural environments."
Construction on the expanded aquarium will begin in 2019 and be completed by 2021.
"Maybe this has galvanised them, hearing each other's stories and knowing they are not alone," say the nurses behind the Facebook group, New Zealand, please hear our voice.
