Retiring Wigram MP Jim Anderton says he has no regrets about leaving the Labour Party in the 1980s, or the split with the Alliance Party he led almost a decade ago.
Mr Anderton delivered his final speech in Parliament on Tuesday, after 27 years as an MP.
He quit Labour in 1989 over economic policy and went on to form and lead the New Labour Party, the Alliance and the Progressives.
Mr Anderton says the fourth Labour government widened the gap between rich and poor hugely, and in his view the country has never recovered.
He says change may have been necessary, but the scale, timing and impact of the Rogernomics revolution was borne by poorer New Zealanders.
