Aotea Lagoon is an artificial lagoon and public park, covering 7 ha,[1] in Papakowhai, North Island, New Zealand. The lagoon formed when transport links were realigned from the natural coastline to land reclaimed from Porirua Harbour.

[edit] Hydrology

Aotea Lagoon is tidal. The culvert, from Porirua Harbour,[2] enters the lagoon under the model windmill.[3] Three stormwater drains flow into the lagoon,[2] two from the east and one from the south-east under the pier.

The lagoon's "water body receives limited flushing and aeration" and "little can be done to improve water quality without extensive engineering works."[2]

[edit] History

Between 1958 and 1961 a causeway was built in Porirua Harbour to realign the North Island Main Trunk Railway.[4] Running north-east from the city centre to Paremata, the causeway cut straight across three bays turning them into lagoons:

  • southern - south of the Gear Homestead headland
  • central - that became Aotea Lagoon
  • northern - north of the headland where Thurso Grove now stands, around Papakowhai Reserve

To realign State Highway 1 inland of the railway the lagoons were partly filled with material from the Ministry of Works and Development's local earthworks. These included the central lagoon's eastern and southern neighbours: the Royal New Zealand Police College and Whitford Brown Avenue. The Ministry and local service clubs transformed the area around the central lagoon into a public park that opened in 1980, Porirua City Council took over the park in 1994.[5][4]

The park's centerpiece is the lagoon and its perimeter path used for walking and running.

South-west of the lagoon is Pipitea Station on the ¼ scale Aotea ridable miniature railway that features an 833 m long track,[6] two bridges and a tunnel. Built and operated by the Waitangirua Lions,[5][4] the train runs:
