This is the most recent financial statement for the Taxpayers Union submitted to the Register of Societies, covering 2017. Not sure why there are no statements from 2018 and 2019, but...

These are no wages in these accounts, only $163,585 in 'personnel and contractor expenses'. However they've claimed 9 employees under the covid wage subsidy.

Even on minimum wage salaries, 9 employees would cost at least $360K per year, but I'm guessing they'd be closer to 80K per year i.e. ~$720K, taking ACC, kiwisaver etc into account.

In 2017 their income was only $355K, but with nine incomes we're looking at another 360-720K. Are we to believe they've doubled or tripled their income in the past two years?
