The 53-year-old presenter currently hosts hit Lotto show In It To Win It.
The new show - called We Know Where You Live - will reportedly earn Winton £750,000 for a two-year deal.
Winton said of the new show: "My association with Lottery shows goes back many happy and successful years. This exciting new extension means that I can give my full commitment to the extra Lottery programmes and hopefully make even more viewers very happy."
We Know Where You Live will see individual contestants paired by mutual postcodes to put their local and general knowledge to the test.
A pilot for the new quiz show will be screened later this month, with the full series expected later in the year.
