The greens here
9 greens at Lake Brunner have been mapped from the national LiDAR survey — 1,285 m² of putting surface altogether, with a median green of 138 m². That puts them in the smallest tenth in the country — 65% below the national median of 397 m².
- Steepest green: green c, averaging 4.7% and falling south-west.
- Flattest green: green h, at 0.5%.
- Most internal fall: green c, 0.62 m between its low and high point.
- Largest green: green g, 177 m².
Every green

| Green E | 124 m² | 0.61 m | 1.1% | south |
| Green F | 134 m² | 0.55 m | 3.1% | south-west |
| Green G | 177 m² | 0.61 m | 4.0% | north |

| Green I | 112 m² | 0.55 m | 4.0% | south-west |
“Fall” is the height difference between the lowest and highest point of the putting surface. “Avg grade” is the best-fit plane across it — a green can average 2% and still have a shelf on it, which is what the app shows and a table cannot.
Where these numbers come from
Heights come from Land Information New Zealand’s 1 m LiDAR elevation survey (West Coast, 2020-2022), published openly under CC BY 4.0. Green outlines and hole numbers come from OpenStreetMap under the Open Database Licence. Slope uncertainty on this course works out at ±0.15%.
Slope is measured. Break is modelled — the read in the app is a physics simulation of a ball rolling over the measured surface, and it knows nothing about grain or moisture. The survey predates any green rebuilt since 2022. More about how this is made.
