Assessment comments The following comments were left by the assessors: (edit · refresh) This article says that nobody was on New Zealand at the time of the eruption, stating that the Maori were the first inhabitants of the island. This is patently false, as much evidence exists, and is recorded in many books on the subject, that New Zealand was inhabited by other groups prior to the Maori, including the Moriori, celtic peoples, and others. One such source is found here: http://www.celticnz.co.nz/RaglanRamble.htm —Preceding unsigned comment added by 121.73.39.79 (talk • contribs) That is not widely accepted; see Māori#Origins, for instance. Talk:Māori would be a better place to discuss the issue. -- Avenue (talk) 00:39, 19 December 2007 (UTC)

[edit] Coordinates

Can someone put in a geo.position spot roughly for Taupo?

Use Taupo township (at the north end of the lake), which is 38.41S 176.7E

[edit] Layout broken

The location pic seems to have broken the page layout, a lot of whitespace is showing between the second and third section. —The preceding unsigned comment was added by 203.118.190.86 (talk • contribs) .

Now fixed, at least in my browser. -- Avenue 08:04, 21 August 2006 (UTC)

[edit] Apparently misplaced text on Taupo eruption

The text regarding the effects of a Taupo eruption on the Maori and Japanese cannot possibly refer to the Oruanui eruption since this took place some 26,500 years ago. I believe that this text should be moved to the paragraph discussing the 181 AD eruption . . . I would have performed this edit, but I couldn't locate corroborating support after a quick search this morning. Can someone else confirm that this text move is warranted?

Myasuda 13:29, 29 September 2006 (UTC)

I can't confirm the Maori reference, but it is almost certainly untrue as the eruption was before recorded history, let alone the Maori arrival in NZ. I went ahead and removed the Japanese reference as it's irrelevant to the article anyway. --Tireoghain2 10:26, 4 October 2006 (UTC)

Agree. --Bender235 21:54, 13 December 2006 (UTC)

[edit] Date of last eruption (AD 181)?

What is the source for the date (AD 181) of the most recent eruption? And what is the range of uncertainty of the date? It seems to me that the evidence for this date ought to be cited in the article. Richwales 04:30, 26 December 2006 (UTC)

I believe the latest date is 230 AD. I can't remember the specific evidence, but it was given in a talk by Dr Colin Wilson (of IGNS, who is one of the authorities on the TVZ). It is cited in a book on NZ volcanism by Bruce Hayward and Geoffrey Cox, and I know Dr Hayward would not give the date if he didn't have good reason to believe it.

I looked up this date; it is quoted in Sparks, R.J., Melhuish, W.H., McKee, J.W.A., Ogden, J., Palmer, J.G., Molloy, B.P.J. 1995. 14 C calibration in the Southern Hemisphere and the date of the last Taupo eruption: evidence from tree-ring sequences.

[edit] Presence of Eels within Lake Taupo

The reference to the presence of Short finned Eels in Lake Taupo is incorrect, and is fact one of the more unusual facts about the lake.

Nztayls 09:10, 4 April 2007 (UTC)

There are no eels in Lake Taupo, the reason for this is that eels need to go to the sea to spawn, and between Lake Taupo and the sea there are the Huka Falls, although adult eels would be able to go down these, the young eels returning from the sea would not be able to go back up them.

[edit] Nitrate leaching into Lake Taupo

Perhaps a section should be introduced on the evidence collected by Doc,Environment Waikato etc, which shows that the clarity of the water has been getting steadily worse over time. The test involves dropping a white disk into the water until it cannot be seen. Nitrate leaching due to farming runoff has implications on the trout fishing industry where the numbers of smelt have been steadily decreasing along side the average size of Trout based on published Doc figures. --Zven (talk) 04:48, 6 May 2008 (UTC)
