Kapuni is an onshore gas/condensate field located on the southern side of Mount Taranaki 85 kilometres from New Plymouth. It was discovered in 1959 by a joint venture of Shell BP and Todd Energy. Commercial production from Kapuni commenced in 1970 making it the first field to be developed in New Zealand. Kapuni was the primary source of domestic gas until Maui production commenced in 1979. Production is tied back to the Kapuni Production Station for processing.
