Documentation added 1993-07-12

Wellington 690/011 RLR(1961) is 9.0m below BM K80/1

Documentation added 2003-01-17

New data from John Hannah added 17/01/03 which supercedes old data. New data does not have any missing days information. Old data has been backed up.

Documentation added 2003-01-17

New data from John Hannah was for Auckland II, Dunedin II, Lyttelton II and Wellington II.

Documentation added 2005-10-17

There is a new John Hannah paper referring to New Zealand data for Wellington, Dunedin, Lyttelton and Auckland. The reference is: "An updated analysis of long-term sea level change in New Zealand." Geophysical Research Letters, V31, L03307, doi:10.1029/2003GL019166 (2004).

Prior to 1984 data were provided by authority 53 (Land Information New Zealand) and subsequently by the Royal NZ Navy (authority A5). Data for 1991 onwards are now provided by authority Department of Land and Survey N.Z. once again.

From information provided by LINZ in August 2006, it seems that there has only ever been one gauge at any one time at Wellington. Since the late 1880's it has been at Queen's Wharf except for a period at Waterloo Wharf during August 1990-August 1994.

Full dataset 1944-2007 received from Glen Rowe at LINZ.

The Kaikoura earthquake of 23:02 on the 13 November 2016 impacted on a number of stations in the central part of New Zealand. Because of this the hourly height values for several stations from 14th November 00:00hrs have been adjusted by LINZ. For station the Wellington the adjust is -0.027m.

Documentation added 2020-08-25

The adjustment due to the KaikĊura earthquake of 2016 has been removed as relative sea level series should include land movement. LINZ now estimate the land movement to be +0.014m

Documentation added 2020-10-13

LINZ have determined that the benchmark 80/1 is unstable, so has been replaced by a new primary benchmark 80/2, which is 9.549m above RLR

Documentation added 2021-08-23

A revised copy of the New Zealand data values for Wellington Harbour has been received from the data supplier the Land Information New Zealand (LINZ). The revised data begins from 2014. This exercise has been carried out to correct some anomalies with the high frequency data.
Adjustment has also been applied to the data to account for the Kaikoura earthquake by creating a new datum TGZ December 2016 3.565m below benchmark K 80/2.
Consequently, the Metric data has had the effect of Kaikoura removed but the effect of the earthquake is still evident in the RLR data.
