In context: how this plant compares
At 360 MW, Waikato power station is well above the median gas plant in New Zealand (112 MW). Technically it is described as OCGT. Its current lifecycle status is “Pre Construction” — so it is not yet, or no longer, generating at full output. Gas plants burn natural gas either in open-cycle turbines for fast peaking, or in combined-cycle units that recover exhaust heat in an HRSG to reach roughly 55–62% efficiency — the cleanest-burning fossil option.
