Nový Zéland - NBL

The 1980s ushered in a period of exceptional growth and popularity for basketball in New Zealand. Late in 1981, six men's teams – a mixture of club and provincial representative sides – went out alone and created an inaugural national league. It was enough of a success to come under the control of the New Zealand Basketball Federation the following year, when it grew in size and secured a naming sponsor. An allowance of two imported players (invariably Americans with college basketball experience) per team, and the fact that games were played in the evening indoors, helped turn the league into a new family entertainment option. Spectators filled gymnasiums and media coverage reached unprecedented levels. The early 1990s held dwindling fortunes for New Zealand basketball and many teams in the NZNBL, with reduced TV coverage, sponsorships, and crowd numbers. With the success of the Tall Blacks at the 2002 FIBA World Championship and the introduction of the New Zealand Breakers in the Australian NBL in 2003, basketball in New Zealand rose in popularity again.

The number of teams each season has constantly changed since the league's inception, with many promotions and relegations between the first division and second division during the 1980s and 1990s, as well as many withdrawals due to financial reasons. The league began with 8 teams in 1982, then peaked at 13 teams in 1995, before dropping to a low of 7 in 2016. In 2019, the Southern Huskies from Tasmania became the first ever Australian team to join a New Zealand competition. The league returned to 7 teams in 2020 following a revised small-scale format due to the coronavirus pandemic. In 2022, the league was hailed for reaching competitive balance after years of unbalanced competition, with evenly spread talent and resources across the ten teams.
