At the very least, Richard Prebble will bring a high rate of activity and profile to his role as Act's campaign manager. He should also deliver the sort of political nous that was demonstrated when he led the party to nine seats in Parliament at its high-water mark in 2002. Mr Prebble, however, is also associated with the old Act, an entity that became so dysfunctional and discredited that its new leader, Jamie Whyte, symbolises the need for a fresh start.
For the party to make a success of that, it must come up with new and innovative policies. In that context, Mr Prebble's announcement that Act would likely revive its flat-tax policy does not bode well.
In his defence, the policy does hark to the principles espoused at the founding of the Association of Consumers and Taxpayers in 1993. Broadly, these embrace individual freedom, personal responsibility, small government and lower taxes. During Act's decline, these faded from view as the party became more associated with perk-busting and the like. Dr Whyte says that he wants to take the party back to those principles.
"The best known of those policies is Act's belief that the fairest sort of tax system is a flat tax where everyone pays the same rate," he says.
That might make sense in terms of party principle. But it hardly offers anything new or innovative. Nor is it likely to gain any traction. Act may have been encouraged to return to the policy by the apparent success of flat taxes in some of the former states of the Soviet Union, and references to the merit of the policy by the Australian Prime Minister, Tony Abbott. But if New Zealand voters failed to share that view in the 1990s, there is even more reason to think they will reject it now.
