The Maori MPs are Kelvin Davis, Shane Jones, Parekura Horomia, Nanaia Mahuta, Mita Ririnui and Moana Mackey.
Te Tai Tonga changed allegiance to the Maori Party at the last election, and although winning back the electorate was a consideration during the visit, caucus spokesman Mr Davis told the Otago Daily Times the main purpose of the visit was listening to the issues that concerned Maori people in this area.
The Maori MPs, accompanied by Dunedin South MP Clare Curran, Dunedin North MP Pete Hodgson and list MP David Parker, from Dunedin, spent Tuesday in Invercargill and yesterday in Dunedin, with a trip to Karitane included.
Ms Curran believed it was the first time the full Labour Maori caucus had visited the city.
Mr Davis said the visit also gave the caucus members the opportunity to support their pakeha colleagues.
"If we can get a foot into Maori groups, it strengthens the community relationship already there."
It was not just about Maori MPs acting on behalf of Maori voters.
Maori voters should know that Ms Curran and Messrs Hodgson and Parker were in the city permanently and could be called upon to act on their behalf.
Mr Davis, also the party's association spokesman for education, met Maori tertiary students and hoped to bring Labour's education caucus back to the city to spend a day visiting educational facilities.
The issues the MPs heard about were the same throughout the South - ACC, the planned rise in GST, unemployment and the loss of jobs, planned changes to the foreshore and seabed legislation, mining in national parks and Whanau Ora, the programme launched by Maori Party co-leader and Associate Social Development and Employment Minister Tariana Turia.
Mr Davis said there were still no details available about the aims of the Whanau Ora programme.
