Labour's trailing National in the latest poll -- and Te Pati Maori again holds the balance of power

The leaked poll findings from Labour's private pollsters, Talbot Mills, are for its corporate clients - not the Party.

The results have Labour at 33 percent behind National's 36 -- with the Greens on eleven, one point ahead of Act.

Both blocs would come up short of the 61 seats required to form Government.

Te Pati Maori is on three per cent, giving them four seats -- and the balance of power.
