Greens Party economics 101.
In May 2025, the Greens released an alternative budget which included stating that their proposed tax changes, including the wealth tax, would raise the government's tax revenue to approximately $200 billion PA. This included, again from their alternative budget, raising $72 billion over four years from it's proposed wealth tax... an average of $18 billion each year from that wealth tax. That means that 9% of the annual tax revenue would come directly from the wealth tax.
But there's a huge problem with their projections. Norway is the only country where the wealth tax is national (Spanish regions can alter their wealth tax such as Madrid and Andalusia which off a 100% effectively meaning there is no wealth tax there and Switzerland's is regional). So, off all the countries in the OECD, Norway is the only country to have a fully nationalised wealth tax. The wealth tax is set at a much lower threshold than that proposed by the Greens and at a higher percentage. Yet, their wealth tax only generates 1.5% of their total tax revenue.
So how, the NZ Greens expect to be able to raise four times the amount of tax with higher thresholds and lower tax rates.
Sorry, but it doesn't add up.
The Green Party says its would raise $88 billion in taxes over four years to expand public services and reduce poverty if able to lead a government
