Auckland will host sailing's 49er, 49erFX and Nacra 17 world championships in November and December 2019.
The event is likely to coax Kiwi sailors - including the likes of 49erFX duo Alex Maloney and Molly Meech and four-time 49er world champions and America's Cup winners Peter Burling and Blair Tuke - into local competition.
It is also likely to double up as a qualifier for the following year's 2020 Tokyo Olympics, for both Kiwi and foreign sailors.
New Zealand - which claimed sailing's greatest prize, the America's Cup, last year - has not hosted a senior Olympic-class world championship since 2015.
That event was the Finn Gold Cup, held in Takapuna.
"The world championships are a big deal for Molly and I and we will be aiming to win it on home waters - it'll be an amazing opportunity for the Kiwi sailors to showcase our sport at a high-level competition," Maloney said.
Torbay also hosted the 2016 youth sailing world championships.
The event will be staged at the Royal Akarana Yacht Club, where construction on a large marine sports centre will be completed this year.
