The 2021 New Zealand Women's National League was the first scheduled season of the new National League since its restructuring in 2021. It was the nineteenth scheduled season of national women's football and was planned as a hybrid season, with four teams from the NRFL Premier League representing the Northern Conference, Central Football and Capital Football representing the Central Conference, and Canterbury United Pride and Southern United representing the Southern Conference.
New Zealand Football announced on the 14 September that they had decided to terminate the remainder of the Northern League season and cancel any yet to be played fixtures due to COVID-19 and Auckland being in Level 4. The decision was made because they couldn't complete all the games before Championship phase was due to begin.
On the 2 November, after confirmation that the alert levels would not change to allow the Auckland and Waikato teams to play any further part in the National Competition, New Zealand Football announced that they were cancelling the remainder of the National League. In its place, they instead decided on a one-off interregional competition, the National League: South Central Series.

The table lists the positions of teams after each week of matches. To preserve chronological evolvements, any postponed matches are not included in the round at which they were originally scheduled, but added to the full round they were played immediately afterwards. For example, if a match is scheduled for round 13, but then postponed and played between rounds 16 and 17, it is added to the standings for round 16.
