Heretaunga is a suburb of the city of Upper Hutt, located in the lower (southern) North Island of New Zealand.

The Heretaunga Railway Station on the Hutt Valley Line serves the suburb.

[3] The settlement, one of the older suburbs in the Hutt Valley, dates from the 1840s when European settlers sought country sections.

[5][need quotation to verify] A prime example of a "leafy" suburb, Heretaunga includes quiet tree-lined streets.

The stream passes around Heretaunga Park and the perimeter of the playing fields of St Patrick's College, Silverstream.
