After the match Whitelock said the team had expected Auckland's vigorous start, in which they scored a converted try through Hadleigh Parkes in the opening two minutes and played with an energy and commitment, especially up front, which appeared to rattle Canterbury.
However, the red and blacks were clinical when they got their opportunities - Tom Taylor twice scoring first-half tries - his second in the closing minutes of the opening stanza despite wing Telusa Veainu cooling his heels for an intentional slap-down as Auckland threatened.
Taylor's kicking and a try to Veainu effectively shut the gate on Auckland after the break. With their forwards tiring, Canterbury got their momentum back which led to an increased line speed on defence and life was made difficult for Wayne Pivac's men.
While Auckland's scrum was dominant, and the second-half entrance of prop Charlie Faumuina added to this, their lineout was poor and Canterbury took advantage.
"The lineout was outstanding," captain Whitelock acknowledged. "We did a lot of work during the week and we came up with a plan that worked."
Flanker Whitelock, who capped off an outstanding season with another big game, took advantage of a sloppy Auckland set piece to help set up Taylor's second try.
It was a tough way for Auckland captain Daniel Braid to celebrate his 100th and possibly final game for the province.
Another favourite saying in red and black country is the one about a player or team's greatest strength also being their greatest weakness.
Auckland's fullback Charles Piutau's liking for running over kicking would have been targeted by Canterbury and his decision to run back an Andy Ellis clearance ended with a turnover and Veainu's try.
On such things do titles, and dynasties, rest.
Canterbury 31 (Tom Taylor 2, Telusa Veainu tries; Taylor 2 cons, 3 pens; Tyler Bleyendaal drop goal) Auckland 18 (Hadleigh Parkes, Lolagi Visinia tries; Gareth Anscombe con, 2 pens). HT: 15-13
