WELLINGTON: New Zealand Prime Minister Christopher Luxon said on Wednesday (Aug 12) he had won a confidence vote of ruling party lawmakers, after he called a meeting to address increased speculation about his leadership months away from a general election.Luxon, who also survived a confidence vote in April, has seen support for his National Party remain weak in opinion polls due to sluggish economic growth, and his personal popularity has declined after a series of missteps."There was a confidence vote in my leadership this morning at our caucus meeting and I have the full support of our caucus," Luxon said in brief remarks after he had called an urgent, in-person meeting in Wellington on Wednesday morning.National's support has weakened as the economy struggles, with unemployment at an 11-year high and inflation above the central bank target of 1 per cent to 3 per cent. Most polls show National narrowly trailing Labour, though the Nov 7 election remains close.A 1News Verian poll published on Wednesday showed Luxon's preferred prime minister rating fell 1 percentage point to 17 per cent, although he remained ahead of Labour Party leader Chris Hipkins, whose rating also fell 1 point to 15 per cent.Luxon's leadership returned to the spotlight after a series of public missteps, including comments about a possible referendum on the country's electoral system, made without consulting party colleagues.Luxon, a former CEO of Air New Zealand, also told a business audience to "be adult" rather than look to the government for help.
