In the
1999 election, Horomia stood as the
Labour Party candidate for the
Ikaroa-Rāwhiti electorate, a
Māori electorate on the east coast of the
North Island, stretching from
Gisborne to
Upper Hutt. He defeated
Derek Fox, a prominent figure in Māori politics, who was standing as an independent candidate. In the new Labour government formed after that election, Horomia became a minister outside cabinet, being Associate Minister of Māori Affairs, Associate Minister for Economic Development, Associate Minister of Employment, and Associate Minister of Education. In 2000,
Dover Samuels was forced to step down as Minister of Māori Affairs after criminal allegations were made against him, and Horomia was appointed in his place. Although Samuels was cleared, it was decided that Horomia would retain the Māori Affairs portfolio. Labour was defeated in the
2008 general election, but Horomia retained his seat – increasing his majority to about 1600. This was despite a challenge from well-known broadcaster Derek Fox. == Achievements ==
