Peter Wilson: Week in Politics - National aims for maximum voter impact

National revealed an enticing tax policy this week, aimed straight at what it calls "the squeezed middle".

That's middle New Zealand, where the most votes are, that big slice of the pie that the main parties need to win an election.

The headline figures in National's "Back Pocket Boost" package, taken from its media statement, are impressive:

Mike Hosking: National’s tax plan shows the battle of ideologies

What makes the National Party's tax plan a winner is severalfold.

1) It's substantive. It's not pocket change. For many it is a material boost to their income.

2) It starts from day one, so what you get arrives immediately, not after years.

National has released their tax policy and it is rather more detailed than anything we have seen from the Labour Party. Predictably, Labour has rubbished it, but it certainly looks like Nicola Willis has put considerable thought into this policy.
