Labour's new shadow Cabinet features five newcomers and pits deputy leader Annette King against National's rookie Social Development Minister Paula Bennett.

Labour leader Phil Goff announced a lineup today that included five promotions to the frontbench and five newcomers to the shadow Cabinet.

The five MPs promoted into the shadow Cabinet are Charles Chauvel, climate change and energy, Moana Mackey, rural affairs and research and development, Sue Moroney, early childhood education, Winnie Laban, Pacific Island affairs and Mr Hughes.

Mr Hughes and Ms Laban were ministers outside Cabinet in the previous Labour-led government.

Mr Goff earlier said there was a mix of old and new in the lineup.
