Hampson will help launch the new discount retailing tie-up between Sainsbury’s and Netto.
He moves across from Sainsbury’s where he has worked for eight years.
Earlier this month, Sainsbury’s announced it was planning a move into the discount grocery market by bringing the Netto brand back to the UK.
The Netto banner, which was last seen in the UK four years ago, will focus on every-day low prices for transparent pricing.
Hampson's most recent position at the supermarket chain was head of its new business marketing where he worked on the launch of Netto and Mobile products.
He previously held the positions of head of brand planning and head of national advertising.
He worked on well-known campaigns such as “Feed your family for £50”, Brand Match and “Live Well for Less”.
The tie-up will involve 15 Netto stores opening in the UK by the end of 2015.
