Milldale is a suburb of Auckland, 33 kilometres north of the city centre.

Construction of the suburb began in 2019, and will take approximately 12 years to complete.

[3] The development, which is planned to accommodate 4500 new dwellings on a 300 hectare site includes a town centre, schools and a retirement village[4] In 2022, the developer of the suburb, Fulton Hogan, purchased a further 191 hectares of farmland adjacent to Milldale, known as Longburn Farm.
