Chlöe Swarbrick: Green Party co-leader on the party correcting their tax policy error

The Greens say they've 'had words' with one of the country's most well-known economists over a maths mistake in its tax policy. It's issued a correction, saying the policy released yesterday will increase net revenue $5.15 billion dollars in the 2027/28 financial year - not $5.35 billion.  Co-leader Chlöe Swarbrick says consultancy Infometrics - headed by Brad Olsen - had the job of analysing the policy figures.  "It was supposed to be our insurance. This is, I think, just human error - and I know that Brad is also more than willing to front up for this." LISTEN ABOVESee omnystudio.com/listener for privacy information.
