Kitson joined Aviva from Norwich Union. He has worked for the company for more than 14 years. He was involved in the early growth of Norwich Union Direct and the recent Aviva rebrand.
Kitson said: ‘This is a personal choice to have a rest, go fishing, write a book, go to Norwich City FC away games, and take stock.'
The Aviva sales and marketing team will be restructured over the next month. Kitson's replacement will be announced at a later date.
