In New Zealand at least, a lot of this data seems to come from imagery; it's quite outdated, the cables are all missing and the voltages are pretty hit and miss. Cool project though.

If you want more up-to-date/accurate data on NZ transmission infrastructure there is also the following "Point" geometry tagged per OSM conventions:
[1] Transpower pylons: https://alltheplaces-data.openaddresses.io/map.html?show=htt...
[2] Transpower substations: https://alltheplaces-data.openaddresses.io/map.html?show=htt...
The public source of this data (ArcGIS Feature Server account of Transpower) shows data last modified by Transpower in October 2025 for pylons and February 2025 for substations. At the rate of development of NZ, you wouldn't expect major changes to any of this data unless it's a major transmission upgrade project identified years in advance in hundreds of public announcements and documents.
For distribution, the largest distributor in NZ (Vector) provides "Line" geometry at https://www.arcgis.com/apps/mapviewer/index.html?url=https:/... (note: not included in AllThePlaces due to ATP not currently collecting geometry other than points)
You can update the data in Open Street Map. Theres a lot of incorrect data in there, but it can only be as good as the data thats been entered.
