Mackenzie, whose global role will give her a seat on Aviva's executive committee, is joining at a difficult time for the group. Last November it cut its marketing team by 140 and its budget from £180m to £100m. It also axed several senior marketing roles in a restructure (Marketing, 20 November).
Mackenzie will join the company on 3 March and be based at Norwich Union's London offices.
Centrica chief executive Sir Roy Gardner and managing director Mark Clare drafted in Mackenzie three years ago to build the British Gas brand. Both have since left the company, being replaced by Sam Laidlaw and Phil Bentley respectively.
Mackenzie's exit comes amid price hikes in the utilities sector and leaves British Gas with a dearth of senior marketers - former head of brand advertising and marketing services Jane Bednall joins InterContinental Hotels Group this week.
Mackenzie will be replaced on an interim basis by British Gas senior marketing manager Andrew Hogan.
