Moonshine Valley is a thinly populated valley with a population of around 201 in the Porirua area of the Wellington Region, centred on the Moonshine Hill Road which leaves State Highway 58 near Judgeford and goes over the Tararua Range to the Riverstone Terraces (formerly known as Craigs Flat) area of Trentham and joins River Road, Upper Hutt.
BRANZ, the Building Research Association of New Zealand headquarters is at the beginning of Moonshine Road near Judgeford.
The valley was settled in the 1860s by settlers including Ephraim Greenwood who had a sawmill and farm.
In World War II there was a camp for the US Marines with a recreation hall and a vehicle servicing depot in the Moonshine Valley.
