Your name and the points you receive at events are entered into the appropriate age and course classes.

You may compete in a course at an AOS event and have your result published without being part of the series competitions. If you do not wish to take part in a competition or there is an error in the age class in published results please advise us at


You must be a member of a New Zealand orienteering club to be awarded AOS points and you must be a member of an Auckland club to be eligible for an AOS certificate. You will not earn AOS points in a second course you do at an event. Please advise registration at an event if you are registering for a second course.

AOS points

The points you receive for a race are based on the course you enter and how well you did compared with the others in your course. Those running the average time for a course will score points equivalent to the weighting factors given in the table below.

The points above and below this are calculated using the difference between your time and the mean time. People from the same age-class may do different courses.

Course Weight
Red 1 90 (80)
Red 2 70 (70)
Red 3 50 (60)
Red 4 35 (50)
Red 5 25 (40)
Orange Long 25 (35)
Orange Short 20 (30)
Yellow 15 (25)
White 10 (20)

Course planners and controllers are awarded points for their event following the last AOS event and is equal to the largest of the points earned in the other events.

Points Calculation

Calculation of points is done using the Standard Algorithm of the orienteering event results program SportSoftware.

   Points = 1000 + (200 * (Course Mean Time - Runners Time) / Course Standard Deviation) 

The points are then adjusted based on the course weighting and divided by 10 to give top scores of around 100 points per race.

   Adjusted Points = Points / 10 * Course Weighting

When mean time and standard deviation are calculated for a course, only those runners' times from the list of grades in the Course Lengths table will be used. This stops the skewing of points caused when top runners run down in a shorter course and get a fast time compared to the regular runners on that course. All runners are given points based on the calculation, even those that are running down in a lower grade.
