| 26 Apr 2010 | Gridref changed from: L37:3558-9789 to L37:35649-97868 and set to an accuracy of QAR 2 |
| 26 Apr 2010 | Visited for well QA 22/4/10. Grid ref and photos updated. GWL access changed to NO. |
| 03 Nov 2011 | Diameter is insufficient replacement bore is L37/1763 |
| 10 Jan 2023 | Reference Level updated using LiDAR imagery in Dec 2022. The existing RL was 22.88 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 21.517m to 21.877m. |
| 18 Nov 2024 | Based on desktop analysis in 2022, it is likely that this well, L37/0431, was replaced by well L37/1763 |
