David Seymour’s plans to break up the supermarket duopoly w/ Emeritus Professor Tim Hazledine: 15th July, 2025

ACT Party leader David Seymour announced plans to address the supermarket duopoly at the party summit on Sunday. Seymour proposed that international competitors haven’t begun operations in New Zealand due to restrictive approval processes. 

Seymour says that while his opponents have proposed breaking up the duopoly or imposing taxes, his solution of introducing a third competitor would be the only truly effective answer. 

Wire host Castor spoke to Emeritus Professor of Economics, Tim Hazledine, about his thoughts on Seymour’s proposal and alternative solutions to break up the New Zealand supermarket duopoly.
