Kiwis should have their say on whether or not New Zealand should implement a wealth tax, says Newshub. On Monday, the Prime Minister didn’t explicitly rule out implementing a wealth tax in the future. A wealth tax is “imposed on an individual’s net wealth, or the market value of their total owned assets minus liabilities”. At the 2020 election, the Greens called for a 1% tax on individuals’ net wealth over $1 million.
