The area was named by Mark Stoddart for the glint of sunlight on water. He bought 500 acre of land in the area in 1856 to farm. The name also applies to the bay within Lyttelton Harbour / Whakaraupō adjacent to the settlement. In 1949, the bay's name changed from Te Waipapa Harbour to Diamond Harbour (Te Waipapa). In 2003, the name changed further to Te Waipapa / Diamond Harbour.

Godley House was built in 1880 by Harvey Hawkins (a ship chandler, ironmonger and financial speculator) on land purchased from Mark Stoddart. This large family home was renowned for parties with party goers arriving on Harry Hawkin's steam launch, the Waiwera. Hawkins went bankrupt and the house and contents were auctioned off in 1896. It did not sell and the Stoddart family, as secured creditors, acquired the property and moved in until the death of Anna Stoddart in 1911. Her daughter Margaret Stoddart lived there also and painted several pictures of Godley House. • Illustration — Godley House, having suffered extensive earthquake damage The property was then sold to the Lyttelton Borough Council. At that time it was named Godley House after John Robert Godley. Godley House and the land surrounding it was made a recreational reserve in 2006. It was used as a hotel, restaurant and conference centre prior to the September 2010 Canterbury earthquake. Godley House was badly damaged in the September 2010 earthquake but it was thought that it could be repaired. However, damage caused by the February 2011 earthquake resulted in the Category II Historic Place being demolished.

Stoddart Cottage, built for Stoddart's wedding in 1862, is the oldest building still standing in Diamond Harbour. It was registered by the New Zealand Historic Places Trust as a Category I historic building in 1990. The artist Margaret Stoddart grew up in the cottage. It is open on weekends and public holidays. It hosts art exhibitions on occasions.
