Following a year and a half of inactivity, Wensink was released by the Blues and signed as a free agent with the Boston Bruins in the fall of 1976. Over the course of the next four seasons, Wensink patrolled the wing in Boston and during the 1978-79 season registered a career high 28 goals and 46 points.
In the 1980 Waiver Draft, the Quebec Nordiques acquired the Cornwall native who went to play one season in "La Vieille Capitale" before signing as a free agent with the Colorado Rockies the following year. After one year in Colorado, Wensink and the Rockies franchise relocated to New Jersey and became the New Jersey Devils.
