New Zealand's own teal wave crashes into campaign

Key points

• Opportunity, a new centrist party led by Qiulae Wong, is polling about six per cent and could win seats at New Zealand's November 7 election. Its MPs could decide which major bloc governs, as it is open to working with either National or Labour.
• Prime Minister Chris Luxon has warned supporters against backing the party, saying he could not govern with it. Under the mixed-member proportional system, smaller parties such as Opportunity have an easier route into parliament.
• Commentators say the minor parties are benefiting from voter frustration with the major parties.
