Jacinda Ardern was on track to achieve an unprecedented outright majority in New Zealand's general election Saturday after campaigning on her success handling the Covid-19 pandemic.With 10 percent of the vote counted, Ardern's centre-left Labour Party was on 49.9 percent, which would give it 64 seats in the 120-member parliament.No leader of any political persuasion has achieved an outright majority since New Zealand adopted a proportional voting system in 1996, leading to a succession of multi-party governments.While the figures are early, they exceed pre-election opinion polls and, if they remain consistent, would represent Labour's strongest showing in decades.Opposition leader Judith Collins' centre-right National Party was on 26.0.
