Hauraki-Waikato is a New Zealand parliamentary Māori electorate first established for the 2008 election. It largely replaced the Tainui electorate. Nanaia Mahuta of the Labour Party, formerly the MP for Tainui, became MP for Hauraki-Waikato in the 2008 general election and was re-elected in 2011, 2014, 2017 and 2020.

In New Zealand politics, Māori electorates, colloquially known as the Māori seats, are a special category of electorate that give reserved positions to representatives of Māori in the New Zealand Parliament. Every area in New Zealand is covered by both a general and a Māori electorate; as of 2020, there are seven Māori electorates. Since 1967, candidates in Māori electorates have not needed to be Māori themselves, but to register as a voter in the Māori electorates people need to declare that they are of Māori descent.
