Sailing has appeared at every Olympics since Athens 1900 - except St Louis 1904 - and was renamed from yachting at Sydney 2000.
Six classes will be contested at Tokyo, four of them - RS:X sailboard, 470, Laser and 49er - by both men and women.
Men's Finn class has been raced since Helsinki 1952 and is the oldest Olympic class.
Sailing has been New Zealand's third-most successful sport at the Olympics, behind rowing and athletics, with nine gold and 22 medals overall.
America's Cup heroes Peter Burling and Blair Tuke captured 49er gold at Rio 2016, after carrying the NZ flag into the opening ceremony. They will seek to defend their title at Tokyo.
New Zealand has a particularly fine record in sailboarding, where Tom Ashley (Beijing 2008), Barbara Kendall (Barcelona 1992) and brother Bruce (Seoul 1988) have all claimed gold. We won't be represented in this event at Tokyo.
Alex Maloney and Molly Meech will try to improve on their 49er FX silver at Rio, while Sam Meech will try to upgrad his Laser bronze.
After a fierce duel with friend and newly crowned world champion Andy Maloney, 2019 world champion Josh Junior has won the right to contest the Finn class at his second consecutive Olympics.
