New Zealand's largest motor vehicle importer and distributor is also Emirates Team New Zealand's most loyal supporter, having first joined the team in 1992.

The 2021 Cup defence in Auckland will be the eighth America's Cup campaign that Toyota New Zealand has been involved in, making it the longest continuous sports sponsorship in the country.

"We've been proud and honoured to stick with the team through thick and thin," said Andrew Davis, the General Manager of Marketing for Toyota New Zealand.

"The team's philosophy of imagination, experimentation and innovation was the winning ingredient in Bermuda last year and represents what we stand for as a company and a country."

"Last year's successful challenge for the America's Cup aligns even more closely with our brand values of continuous improvement and over the last four years this focus led to some exciting innovations and culminated in victory."

"We are really proud to have Toyota back on board with the team again," said Emirates Team New Zealand CEO, Grant Dalton.

"They have been a staunch supporter of the team for over 25 years now since the 1992 campaign. We have grown together and Toyota is very much part of our DNA."

Toyota New Zealand first joined an America's Cup campaign in 1992 and was involved in Black Magic's victory in 1995 and successful defence in 2000.

It has also stood behind the team when the trophy went to Switzerland in 2003 and the challenges in 2007 and 2013.

Toyota's support of Team New Zealand since 1992 is one of the most successful sports sponsorships in the country's history, said Mr Davis.

New Zealand is the second most successful country in the 167-year history of the America's Cup (after America) and is the only country to successfully challenge for the "Auld Mug" on more than one occasion.

"The team has achieved a remarkable success in a short time and it is the people who have gone the extra mile to deliver great results," said Mr Davis.

The 2021 defence of the America's Cup will be contested in AC75 mono-hull yachts, which will be designed to foil, like the catamarans used in the last two contests at San Francisco in 2013 and Bermuda last year.
