Today's Team New Zealand homecoming parade in Auckland will go ahead rain, shower or shine.

Thousands of people are expected to cheer on the America's Cup champions during their one-hour parade down Queen Street.

The parade is likely to bring the central city to a standstill, and cause traffic delays around the city.

Roads around Queens Street and the Quay Street waterfront will be closed as thousands of people cheer on the America's Cup champions from 12.30 this afternoon.

Chamber of Commerce chief executive Michael Barnett said parade-goers should allow time to find a good viewing spot.

"Leave early, make arrangements, use public transport, and most importantly allow time and therefore allow plenty of opportunity to celebrate."

Barnett said it won't be a typical business day, with some people taking the day off work and others knocking off early or watching the parade in their lunch break.

"Employers will probably be a bit flexible about having people out there watching the parade, and so they should. It's going to to be a big day for celebrating the success of these heroes."

The return of the Auld Mug to the City of Sails will mark an historic occasion, with Team New Zealand being the first syndicate to regain the America's Cup.

The parade will follow a similar route to Team New Zealand's victory parade after they first won the America's Cup back in 1995.

Heart of the City chief executive Viv Beck said: "it's great to see the team back and great to see the Cup back," and the parade will be another once-in-a-lifetime event.

"It's particularly exciting for central Auckland to see the parade down Queen Street, which is historically very important for the city.

Excitement has been building for the parade since the first details of the event were revealed on Newstalk ZB last week.

Beck said there's a sense of celebration in the central city, both for today's parade and for the next America's Cup defence in 2021.

"People are lining up to see the team arrive and bring the Cup back to New Zealand, and are generally excited about what this means for the city."

Mayor Phil Goff said he was looking forward to welcoming Team New Zealand and the America’s Cup back to the city.

"While Queen Street was originally ruled out as a parade route, city agencies have worked collaboratively to bring the parade down Auckland's main street.

"The heart of city... is also synonymous with past America’s Cup successes.”

The parade gets underway at 12.30 this afternoon.

Weather forecast 

The central city is forecast to get heavy rain this morning and late this afternoon.

MetService meteorologist Brian Mercer said the weather should settle down for a bit during the middle of the day for the parade.

"From late morning to the early afternoon we are still expecting a few showers. They're not going to be particularly heavy but it will be a little bit damp."

Mercer said the heavens could open as people are making their way home after the parade.

"It will be quite a damp day. The heavy falls are going to be in the morning and or into the late afternoon into the evening."
