Aotea Lagoon is an artificial lagoon surrounded by a 7 ha public park in the Papakowhai suburb of Porirua, North Island, New Zealand. [1] Aotea and two nearby lagoons were created as transport links were realigned from the natural coastline to land reclaimed from Porirua Harbour.

Hydrology[edit]

The lagoon is 5 ha of seawater,[1] connected to Porirua Harbour by a culvert under the model windmill.[2] Three stormwater drains empty into the lagoon,[3] two in the east bank, the third in the south-east under the jetty.

The lagoon's "water body receives limited flushing and aeration" and "little can be done to improve water quality without extensive engineering works."[3] Poor water quality means swimming is prohibited.[4]

History[edit]

The North Island Main Trunk Railway and State Highway 1 used to run round three bays between Porirua and Paremata. In 1961 the railway was realigned to a causeway built between headlands at the mouth of Porirua Stream, Gear Homestead, present day Thurso Grove and Forth Place.[5] Cut off from the sea, the bays became lagoons.

The lagoons were partly filled in, with material from the Ministry of Works and Development's local earthworks,[6] then the highway was realigned inland of the railway.

The Ministry, Porirua City Council, Project Employment Programme and local service clubs turned the area around the middle lagoon into a public park,[2] that opened as Aotea Lagoon in 1980.[7] Originally leased from the Crown, the park was taken over by the City Council in 1994. [2]

Facilities[edit]

The park's centrepiece is a path around the lagoon, the easiest of Porirua's top 12 walking and cycling tracks.[8]

The Waitangirua Lions built a ¼ scale ridable miniature railway with an 833 m loop track including two bridges and a tunnel.[9] The train runs Sunday afternoon, weather permitting, from Pipitea Station south-west of the lagoon.[10]

The park has lawns on three sides, some with barbecues. Other facilities from the north-east are adventure and toddlers' playgrounds, a duck pond crossed by boardwalk, an island reached by bridge and a Pétanque terrain. In the south-west corner are another duck pond, a fernery and a rose garden.

Most people visit Aotea Lagoon to walk for exercise or relaxation while children enjoy the playgrounds, feeding the ducks, riding bicycles and the train.[11]
