This is an interpretation of osm.wiki/Editing_Standards_and_Conventions and osm.wiki/Disputes#Naming, as well as looking at other bilingual countries' names in OSM (e.g. Switzerland and Belgium)

OSM guidelines are to list bilingual names in descending order of speakers, so "New Zealand / Aotearoa" is the correct order.

Accidentally left them over. I've fixed them. :-)

Fixed :-)

I've paused all uploads until the issue is sorted. Juts would like to comment that we've been using Stats NZ boundaries for the regional councils, territorial authorities and Auckland local boards for over 10 years (since at least December 2014) without issue. Not sure if LINZ has this data...

Okay, so I won't import any more SA3 boundaries. That was just a trial for suburb boundaries, so are only in parts of Napier and Palmerston North at the moments. Going foward, we may use LINZ boundaries for suburbs.

Ah, yes. Just haven't got around to doing the cleanup yet.

I'm not sure. I edited it so long ago, so the crietria might have changed.

On what grounds you believe this road meets motorway standard? It has several intermediate at-grade intersections.

The Starlink station is at Hinds, a good 20km to the southwest. This is Seafield electric substation. Have fixed.

Why is SH 21 a trunk road? NZTA defines it as a non-strategic arterial route, similar to nearby SH 26 and SH 39.

Done = changeset/123633677

Have contacted NZTA via Facebook and the confirm it should be 1C and the southbound gantry sign is wrong.

Sorry, my mistake (didn't see access=no)

Transmission Gully is not open yet.

The "Motorway begins" sign is just after the Weedons Road exit heading north, so techinically this section is not a motorway.

This is not a motorway. There is no "motoway begins" sign, there are no restrictions on pedestrians and cyclists, and it still has private protery accesses off it

QEII Drive is not a motorway, since it has intermediate at-grade intersections (i.e. rounabouts at the CNC interchange).

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)
