Forty international boats were turned away from Whangarei's central marinas last year, with an $8.9 million marina on the cards to solve the waterway's parking problem.
Preliminary estimates put the benefit to Whangarei's economy at about $13.3 million annually for the proposed 100 new berths, adding to the $34 million already generated by the local marine industry, according to a preliminary feasibility study prepared for Whangarei Harbour Marina Trust.
The trust was responsible for the 181 Town Basin berths and 109 Kissing Point berths and is investigating setting up its third Hatea River site: 100 berths immediately downstream from Te Matau A Pohe on the west bank, just upstream from Limeburners Creek.
Trust chairman Brian Caulton said the two current central marinas had been operating at capacity for the past 10 years.
"It's all exciting. The industry in Whangarei is growing all the time with refit and shipyards, so we want to grow with that - we want to be ahead of the eight ball," Mr Caulton said.
