The purpose of the New Zealand Golf Handicap System is to make the game of golf more enjoyable by enabling golfers of differing abilities to compete on an equitable basis. The System provides fair Course Handicaps for players regardless of ability, and adjusts a player's Handicap Index up or down as the player’s game changes. At the same time, it disregards high scores that bear little relation to the player's potential scoring ability and promotes continuity by making handicaps continuous from one playing season or year to the next. A New Zealand Golf Handicap Index is useful for all forms of play and is issued only to individuals who are members of golf clubs.

Junior Handicap System
The Junior Handicap System (JHS) has been created to provide a shortened and appropriate golf course set up for young golfers and to provide a system that will motivate and reward beginner juniors to play and improve when they aren’t yet at the ability or physical maturity to have an Official Handicap.
The JHS is a 9 hole junior handicap where juniors can get a handicap after just 9 holes!
Minimal work is required by the golf clubs to set up, where the course starting tees can be from your clubs distance markers (90m, 135m, 180m) so no additional tee grounds need to be made or to interfere with play by other club members.
