Tauranga City Council has decided to install sirens in the community as part of its tsunami warning system.
A council report discussed at an annual plan meeting on Monday found community awareness of the potential for tsunami has increased over the past five years.
The report looked at four siren options including mega-sirens, like those used in the United States to warn of tornadoes.
The council has now opted to have sirens installed on power poles and other poles 10 metres high.
Mayor Stuart Crosby says the network of sirens will cost about $1 million.
He says as well as its practical value, it will help make people feel safer.
