Talk:Mahurangi Harbour

Upper extent of the harbour, vs the river
Nice map but is the harbour really considered to reach as far up as Warkworth? The topo maps say, no, that's the Mahurangi River. The topo map doesn't indicate the exact river/harbour border, but I suspect it is Hamiltons Landing. Nurg (talk) 02:40, 2 September 2022 (UTC)
 * Going by satellite view I'd agree - that's definitely far too high up into the river. I also have issues with the harbour mouth: the harbour should begin at Otarawao Bay/Cudlip Point to the south. I'm not a regular editor of Open Street Map, otherwise I'd attempt to fix this. --Prosperosity (talk) 06:07, 2 September 2022 (UTC)
 * So it seems that east of Wilson Road is the agreed point in council reports/scientific reports ([1][2][3 (page 13)]), but this isn't what's on LINZ, which marks the end of the river as the Elizabeth Street bridge in Warkworth (but LINZ topographical map also lists as far south as Hamilton Road as the river). I've attempted to messily fix this on open street map - hopefully someone can review my edit and fix it up. --Prosperosity (talk) 23:27, 4 September 2022 (UTC)
