Trans. : No Distribution : 1955-2019 Refernce Levl: The sea level heights are referred to the Tide Gauge Zero (TGZ): TGZ is 6.721 m below New Plymouth Fundamental B.M. (LINZ code AGMH), a stainless steel pin set in concrete block, 0.305 m under concrete cover and iron cap on east side of Rigger Shed, Port Taranaki. Comment : The daily values show large peaks of a few days duration associated with extreme weather. Timing is poor prior to 1967 and at select spells there after. The data are relative sea level. The Kaikoura earthquake of 13 Nov 2016 resulted in the local land sinking by 0.012 m, giving a relative sea level rise of 0.012 m. Users who want to remove the land movement can adjust by -0.012 m to the relative sea level for 12Z 13 Nov 2016 - end of record. For more details, contact LINZ.
