This is what we found on Wikipedia regarding the One New Zealand Warriors:

The New Zealand Warriors are a professional rugby league club based in Auckland, New Zealand that competes in the National Rugby League (NRL) premiership and is the League's only team from outside Australia. They were formed in 1995 as the Auckland Warriors, and are affectionately known as the Wahs. The Warriors are coached by Andrew Webster. Mitch Barnett and James Fisher Harris are the current co-captains. The Warriors are based at Mount Smart Stadium in the Auckland suburb of Penrose.

For the 1995 season the newly formed Auckland Warriors became the first club from outside Australia to be admitted to the Australian Rugby League's premiership when it expanded from 16 to 20 teams. As a result of the Super League war in the mid-1990s, Auckland left the ARL to compete in the Super League competition of 1997, before joining the re-unified NRL the following year. They re-branded themselves the New Zealand Warriors in 2001. The club has yet to win a premiership as of 2026. They have won one minor premiership (in 2002), and reached two grand finals (2002, 2011), reaching the finals ten times but always falling short.
