He was an original member of the Vancouver Canucks upon their entry into the NHL in 1970, and also played for the Chicago Black Hawks, as well as the Cleveland Crusaders and Indianapolis Racers of the World Hockey Association, and also spent time in the minor leagues before retiring in 1976.

He would also lead Denver to a memorable triumph over the University of North Dakota in the 1968 NCAA Championship game.

He would establish himself as a quality scorer in minor-pro, but unlike Magnuson and Koroll who both became fixtures in the Chicago lineup for more than a decade, Wiste found the adjustment to the NHL difficult, and found it hard to get icetime on a deep Black Hawk team.

After a 3-game stint in Chicago in 1968–69, he spent most of the 1969–70 campaign with the Black Hawks, but was often a healthy scratch and failed to record a goal in 26 games.

After another season in the minors, Wiste was one of many fringe NHL players to jump to the rival upstart World Hockey Association for the 1972–73 campaign, signing with the Cleveland Crusaders.
