NZASP keeps ratings and rankings lists of players who have played rated games in tournaments in NZ. The Ratings Officer calculates and maintains these lists.
Rankings and ratings lists
The ratings lists include all players who have played in at least one rated tournament in the previous 2 years. If a player returns after a 2 or more year absence the previous rating is applied unless agreed between the tournament organiser and the player.
Rankings and ratings are calculated in the same way. New Zealand ratings calculations are based on a system similar to the United States. A player’s rating depends on the number of wins gained against the opponents played in a tournament, compared to expected wins based on the differential in rating between the player and his/her opponents. A fuller explanation and worked example is given here.
What do GM and E mean on the ratings lists?

1. A player who has five separate post-tournament rankings in the top 20 over a five year period, or three in the last 12 months.
2. A player who has represented NZ in the Trans–Tasman Challenge more than once.
New awards will be made at the end of each calendar year and announced on Slack and in the summer edition of Forwords. The appropriate letters will be added beside each player’s name in both the online and printed ranking lists.
Note. Post-tournament means post a tournament a player has actually competed in so that the number of games played will be more than previously. It is not enough to get one qualifying result and then sit out the next few tournaments.
