The deal keeps the World Cup hero at The 1st Central County Ground until at least the end of the 2022 season.
In an exclusive interview for the Sussex Cricket website, the 24-year-old said: “Sussex gave me my opportunity right at the beginning of my career, so I am very happy to commit long term to the club.
“I really do enjoy playing with everyone here at Sussex and it was really nice to come back down last year to play a few games with the lads.
“It’s the same club that I left it as and it’s nice to know nothing has changed. Sometimes people sit in my space in the dressing room now, but that’s fine!
“It most definitely still feels special to pull on the Sussex shirt.”
