Duncan has served as the MP for Christchurch Central since being elected in 2017. He is currently the Minister of Commerce and Consumer Affairs and Minister for State Owned Enterprises.
Christchurch has faced challenges from earthquakes, terrorist attacks and COVID-19. Duncan is committed to making sure Christchurch gets the investment and jobs it needs and will continue to be a strong voice in a Chris Hipkins-led Government.
Serving in Parliament has allowed Duncan to play a part in making New Zealand a better place through his pivotal roles in climate change legislation, resource management reform and COVID-19 response laws. Prior to entering Parliament, Duncan was a professor, lawyer, and social activist.
He lives in St Albans with his family and has advocated for policies that promote Christchurch Central as a place to live as well as work. He believes thriving businesses, supported by good government policy, are essential to building a just society that cares for all.
