After a difficult week, The Green Party has this afternoon announced a shake-up of what it looks and sounds like, but not what it believes in.

The party has been forced to reset its campaign after a chaotic week in which it lost two long-standing MPs and a co-leader.

Leader James Shaw has today announced a new list and a resurrected campaign slogan, admitting the one they had hoped to use was not suitable.

He says their slogan was "Great Together" but he says over the last couple of weeks they have not been all that together and it has not been all that great.

Instead they will use the slogan "Love New Zealand", which was the party's slogan in 2014.

Mr Shaw has also reshuffled the focus of his front bench.

Marama Davidson is the new poverty spokesperson, Julie Ann Genter is taking climate change and Eugenie Sage will lead on cleaning up rivers.

Mr Shaw said it goes to the heart of what the Greens stand for.

Former co-leader Metiria Turei resigned on Wednesday, saying scrutiny of her family over her past welfare history had become unbearable.

The Greens had plummeted in a poll due to be unveiled that night but she denied that was a reason in her resignation.

Mr Shaw, the party's current sole leader, said the party will focus its policies on poverty, climate change and clean water.

New candidates Chloe Swarbrick and Golriz Ghahraman have moved up into seventh and eighth on the list, almost guaranteeing them a seat in Parliament post-September.
