Thames is a town at the southwestern end of the Coromandel Peninsula in New Zealand's North Island. It is located on the Firth of Thames close to the mouth of the Waihou River. The town is the seat of the Thames-Coromandel District Council. The Māori iwi are Ngāti Maru, who are descendants of Marutuahu's son Te Ngako. Ngāti Maru is part of the Ngati Marutuahu confederation of tribes or better known as Hauraki Iwi.
Many people migrated to Thames at its peak, and it was soon the second-largest city in New Zealand (the largest being Dunedin then Auckland). However, as the gold began to diminish, so did the number of inhabitants, and although Thames never shrank, it has never grown much either. It is still the biggest town on the Coromandel. The population in the 2006 census was 6,756, an increase of 51 since 2001.
