Ahead of tomorrow's official unveiling, the foiling monohull was out on display on the Auckland waterfront.

The unnamed AC75 is a foiling monohull, which Team New Zealand are saying will be faster than its predecessor - the AC50 catamaran called Aotearoa.

Dalton said there are still a lot of checks to be carried out on the high-tech new monohull but tomorrow's launch is a chance to "say thanks to everyone who’s helped us get this far".

Dalton said around 500 people have been invited to tomorrow's unveiling, where a representative from the team's charity, Motor Neurone Disease Association of NZ, will christen the boat by breaking a bottle of champagne on the bow.

But 1 NEWS' camera wasn't the only one present to capture the event today, with a Luna Rossa spy also on hand to grab a few snaps of the new boat design.
