Talk:List of rivers of New Zealand by length

Comments
Should there also be a list of shortest rivers? It seems an arbitrary distinction that a 2km stream such as Tawatahi River has such a name and gets a listing and an article. — Preceding unsigned comment added by Johnragla (talk • contribs) 20:34, 12 January 2013 (UTC) I've now started a shortest list.

Why is the Tongariro River listed as the longest?
The article for the Tongariro River says that the name refers only to the section of the river that flows into Lake Taupo. So why is it, rather than the Waikato River, listed as the longest? Ross Finlayson (talk) 01:17, 6 January 2019 (UTC)

Waiau (Southland) River length
I can't see how Waiau (Southland) River has a length of 217km. I can see that it is listed as such in the source (Te Ara article), but it doesn't add up with the description in the river's main article (Waiau River (Southland)) or with my rough measurements on a map. Another site describe it as 112km: https://www.onnaturesedge.co.nz/tuatapere/whats-here/waiau-river/. Presumably it's a case of different definitions of the river source.

 * The ultimate source is likely on the Eglinton River at The Divide. The length would be the longest distance a drop of water flows in the river basin. Not sure if that helps but that is generally how they're measured. ShakyIsles (talk) 06:37, 14 September 2021 (UTC)
