Mangawhai is a township at the south-west extent of the Mangawhai Harbour, or Mangawhai Estuary, in Northland, New Zealand. The adjacent township of Mangawhai Heads is 5 km north-east, on the lower part of the harbour. Kaiwaka is 13 km south-west, and Waipu is 20 km north-west of Mangawhai Heads.[1] [2]
In 2018 it was proposed to develop a new town between Mangawhai and Mangawhai Heads, called Mangawhai Central, to accommodate the rapid increase of population expected and overcome the space limitations of the existing commercial areas.[3] The business area was largely complete by the end of 2022[4] but the residential development stalled.[5] A new residential area called Mangawhai Hills is planned west of the existing settlement.[6]
Mangawhai is the traditional Māori name for the area, referring to the stingrays which live in the harbour.[7]
In the early and mid 19th century, Mangawhai Harbour was one of the main access points for the Kaipara. Ngāti Whātua used to drag waka from Kaiwaka to Mangawhai.[8] A Ngā Puhi war party landed at Mangawhai in February 1825 and moved 12 km inland to confront the Ngāti Whātua at Te Ika-a-ranga-nui near Kaiwaka.[9] [10]
Later in the 19th century, settlers would travel by boat from Auckland to Mangawhai, walk to Kaiwaka, and then travel on the water again across the Kaipara Harbour. By the early 1860s, a dray road existed between Mangawhai and Kaiwaka.[11] In the latter 19th century, the kauri gum digging trade became an important industry in the area.[12]
Sand mining began at the Mangawhai Harbour entrance pre 1940.[13] In 1978 the collapse of sand dunes, believed to be caused by sand mining,[13] [14] closed the harbour for five and a half years.[15]
From 1993 to 2004, sand was commercially suction-dredged from the sandbars of Mangawhai Heads.[16] In 2004, the Mangawhai Harbour Restoration Society won an Environment Court decision to stop the issue of new licences.[14] The companies such as McCallum Brothers, re-applied to the Auckland Regional Council for resource consent but the application was turned down in 2005.[17]
In January 2008 another application to sand mine in the Mangawhai Forest was being heard by the Environment Court.[18]
