The left of New Zealand politics is just edging the right, revealed the latest Colmar Brunton opinion poll.

The results show Labour, led by David Shearer, the Greens and Mana with 47 per cent support, just one point ahead of the current National - ACT - United Future arrangement.

The poll indicates that were an election held now, the Maori Party could likely hold the balance of power.
