Chris Luxon is standing firm on his opposition to a capital gains tax.

A New Zealand Herald-Kantar Poll shows New Zealanders are evenly split on Labour's proposal for a tax on gains on commercial and investment properties.

Opposition is strongest in Auckland, while support for the CGT is stronger in every other region.
