Prime Minister John Key has accepted with sadness the resignation of Dr Nick Smith from his ministerial portfolios.
The resignation came after intense media questioning of Dr Smith's judgement to support an ACC claimant while he was minister during the previous term.
The following ministers will act in portfolios previously held by Dr Smith: Gerry Brownlee in Local Government, Craig Foss in Climate Change Issues and Chris Finlayson in Environment.
