A senior tax director predicts the Government will propose a capital gains tax and take it to the election.

An Inland Revenue report released yesterday found the average earner is taxed at more than double the rate of New Zealand's wealthiest.

Andrew Dickeson from Baker Tilly Staples Rodway suspects the Government will introduce a broad tax on capital, but it risks running the rich out of New Zealand.

"High net worth do a lot of great things for New Zealand, including employing hundreds, if not thousands of New Zealanders. So if they take their businesses offshore, who's suffering? Ultimately, it's New Zealand as a whole."
