Ms Ardern graduated in 2001 from the University of Waikato (doesn't surprise) with Bachelor of Communications (politics and public relations), then spent time as a researcher for her heroine Helen Clark before skiving off to London.
Shot back to New Zealand for 2008 election, entering Parliament via Labour list and continuing for past nine years, mostly as a nondescript list MP.
She's a committed socialist, gay rights/gay marriage advocate, republican, agnostic, feminist, trade union supporter, pro-choice abortion and carbon tax zealot, plus undoubtedly a Maori separatist/treatyist /race-based policy sympathiser.
The Greens and Labour Maori manifestos are scary, as they pledge to legislate to enshrine Maori as indigenous, promote treaty-based constitution, fund Maori providers for the public sector, connive with local government to reinforce the drive for unelected Maori seats, retain race-based Maori parliamentary seats, promote Maori self-government with a separate legal system.
Ms Ardern's working life has always revolved around politics. She proposes sweeping taxes on water (iwi initiative), land, capital gains, wealth, carbon emissions, plus reinstate death duties, inevitably supporting race-based policies.
