The 29-year-old has taken 63 wickets in 53 matches since joining the county in January 2019 and is looking forward to continuing his impressive life with the Spitfires.
The Dutch national, who has represented his country on 32 occasions, played a major role as Kent Spitfires won this year's Vitality Blast.
"This squad can push on and become a real force across all formats and I'm determined to help make more history for this club," the left-arm seamer told Kent's website.
Kent director of cricket Paul Downton said: "He is ambitious, works hard and wants to play in all formats.
"As he continues to develop his game, he has the ability to be a major contributor to Kent Cricket in the years to come."
