Labour Party leader Jacinda Ardern says voters concerned about stability should look to her party.
"I offer stability, I offer firm, reasonable leadership that is focused on delivering a vision for New Zealand that I think is much, much better than where we are now. If they are looking for stability, they will find it with me," Ardern told Radio New Zealand.
Ardern said Labour remained committed to the memorandum of understanding with the Green Party, but stressed the two parties were separate.
Ardern's comments follow the Greens' announcement it intends to formally suspend senior MPs Kennedy Graham and David Clendon from caucus after they threatened to quit if co-leader Metiria Turei did not stand down from the leadership over her revelations she had committed welfare fraud.
