[eri]

napier had limited land to build on

until the big quake of 1931

lifted the surrounding swamp high enough to self-drain

The local landscape changed dramatically, with the coastal areas around Napier being lifted by around two metres.^[5] The most noticeable land change was the uplifting of some 40 km² of sea-bed to become dry land. This included Ahuriri Lagoon, which was lifted more than 2.7 metres^[5] and resulted in draining 2230 hectares of the lagoon. Today, this area is the location of Hawkes Bay Airport, housing and industrial developments and farmland.
