Ngatamariki is a geothermal power station commissioned in 2013 and operated by Mercury Energy.

It is located approximately 17 km north east of Taupō and was constructed well under the budget of $475 million.

[1][2][3] The field was initially explored by the Crown in 1985-86, with the wells NM1, NM2, NM3, and NM4 drilled to 1300m, 2403m, 2194m, and 2749m respectively.

[2][8] The power station is a binary plant, supplied under an EPC contract by Ormat.

[9] A 220,000-volt power line connects Ngatamariki to Mercury's Nga Awa Purua Power Station, where electricity from both stations is injected into Transpower's national grid.
