David Cunliffe has probably done enough to avoid Labour suffering too much collateral damage from the Shane Taurima affair.
There was a high risk that the surreptitious use of TVNZ resources by Taurima and other Labour activists working in the state broadcaster's Maori and Pacific unit would rebound on Labour and prove to be extremely embarrassing for the party.
There was a danger that their behaviour would leave the impression Labour had no regard for impartiality in news coverage and current affairs programming.
That potential prospect had Labour's leader putting as much distance as possible between the party and Taurima despite him having been a serious proposition for the party's candidacy in Tamaki-Makaurau, one of the seven Maori seats.
Cunliffe might have been tempted to have given Taurima a verbal lashing and even invoke disciplinary procedures laid out in the party's rules.
