Suburbs are not administrative entities so don't have the boundary=administrative tag. Also, admin_level is far too high (2 = country, 4 = region, 6 = city/district)

👍

The sign at the roundabout says "Mwy South". The "Motorway begins/ends" signs are placed beyond the junction to reduce clutter. We don't start the motorway desingation halfway down an off/on ramp where the signs are, do we?

Reverted in changeset/90331514 - the motorway designation begins at the ramp junction, not at the sign. The begins/ends sign is often placed beyond the junction to reduce clutter.

reverted in changeset/82597780 - this road is not a motorway since it has at-grade intersections

Remember to check your spelling. It's "Pahiatua", not "Pahitua".

The regions of New Zealand don't have official Maori names, so dual naming is incorrect.

Partially reverted in changeset/63307642. The motorway was widened from 2 to 3 lanes southbound in May 2017 (see https://www.nzta.govt.nz/projects/southern-corridor-improvements/)

The line names are incorrect - they're the name of the train services that run on them by AT, not the correct line names used by KiwiRail.

Also, Montgomerie Road intersection closed in September 2017 - see https://www.nzta.govt.nz/assets/projects/sh20a-to-airport/docs/SH20A-to-airport-newsletter-Mar18w.pdf

The roundabout was replaced with traffic lights on 19 May 2018 - see https://www.nzta.govt.nz/projects/sh20a-to-airport/landing-drive-changes/
