| 20 Aug 2010 | Gridref changed from: M36:8635-3325 to M36:86372-33267 and set to an accuracy of QAR 2. BCR confirms |
| 10 Jan 2023 | Reference Level updated using LiDAR imagery in Dec 2022. The existing RL was 18. and the QAR RL was 4. The method of calculating the original RL was: Interpolated DTM. If GL from MP is updated in future please assess if RL also needs to be updated. |
| 10 May 2023 | Dec 2022 Reference Level update using LiDAR was in NZVD 2016, rather than Lyttelton 1937. Rectified in May 2023 by using the previously determined LiDAR elevation value and LINZ conversion tool to calculate Lyttelton 1937 elevation and update Reference Level field. Reference Level updated from 3.535m to 3.936m. |
