Labour leader Jacinda Ardern has shown a ruthless streak on her third day as leader, effectively forcing co-leader Metiria Turei to rule herself out of a future ministerial role in a bid to stem the ongoing ructions of Turei's welfare admissions.
In a double-blow for the Greens, Ardern has also chosen the environment as one of the top four policy areas she intends to ramp up in her bid to stamp her own brand on the campaign - a signal she is targeting environmentally-conscious voters in the cities, a core voting pool for the Green Party.
After taking over as leader on Tuesday, Ardern gave herself 72 hours to review the Labour campaign. The results of that were released yesterday and Ardern said it would mean an upgrade to policies on infrastructure, the environment, education and health.
Ardern will make her first policy announcement on Sunday, expected to be on Auckland transport and include a rail link from the airport to the CBD. An environment policy will follow next Wednesday.
Ardern said she wanted the campaign to reach people who didn't vote last election and would be using social media a lot more. Tertiary students are expected to be the main target of Ardern's first big education announcement - she has previously said she was concerned about the cost of education and cost of living for students.
