Tau Henare discusses growing support for Greens on Maori roll

A new poll suggests a surge in support for the Greens among voters on the Maori roll. The Greens have never won a Maori electorate, or finished first in the Party vote in one. But the Mata-Horizon poll found 28 percent would cast their party for the Greens, compared to 27 percent for Labour. Former New Zealand First and National MP and Maori Political commentator Tau Henare spoke to John Campbell.
