nz shares or property

[Zaphod]

I'm amazed that the government (or councils) make bugger all from property sales. Imagine how much a graduated stamp duty tax would bring in! Starting at 2% at $500,000 and over and gradually moving up to 5% on $1,000,000 .... Auckland could have that new harbour crossing paid for in weeks ;o)

In much the same way a financial transaction tax that imposes a fraction of a percentage point could yield the Government billions?
