The 2005–06 New Zealand Football Championship was the second season of the New Zealand Football Championship. The final was won by Auckland City, who defended the title they won in 2005.
In the regular season, all teams played each other three times, as before. But the playoff stage was changed slightly, with the top five teams now going through to the playoffs (as opposed to the previous three).
