This is a list of power stations in New Zealand.

The list is not exhaustive – only power stations over 0.5 MW and significant power stations below 0.5 MW are listed.

Power plants in New Zealand have different generating roles – for baseload, intermediate or peaking. Baseload generators are those that run continuously (except for maintenance), and include all geothermal and run-of-the-river hydroelectric plants, which must 'use it or lose it'. Intermediate generators are load-following power plants. Peaking power plants generate only for minutes or hours at a time, during the sharpest peaks in electricity demand. Nuclear power is not used in New Zealand.
