Trentham (/ˈtrɛnθəm/) is the most populous suburb of Upper Hutt, a city in the Wellington region of New Zealand. The suburb is located in a widening of the Hutt Valley, five kilometres to the southwest of the Upper Hutt city centre.
The suburb includes the Trentham Racecourse, the base of the Wellington Racing Club, the site of Hutt International Boys' School, and the Trentham Railway Station.
The Trentham Military Camp was used extensively for training soldiers in preparation for World War I and World War II. It is still a base for the New Zealand Defence Force.
A General Motors-Holden assembly plant operated in Trentham between 1967 and 1990.
History
The area was settled in the 1840s.
The name "Trentham" was initially given by Richard Barton, the first European Settler in the area, in honour of his former employer, the Duke of Sutherland. One of the Duke of Sutherland's subsidiary titles was Viscount Trentham, of Trentham in the County of Stafford.
The Barton family memory lives on in the area, with Barton Road, Barton Avenue and an area of native trees called Barton's Bush, which is within the reserve now known as Trentham Memorial Park. Richard Barton was interred in the grounds of St John's Church, and there are also memorials to him in the form of brass plaques within the Church building.
