Mitchell Lovelock-Fay won the tour by 41sec from Joe Cooper, with Hayden McCormick a further 2sec back in third place.
Lovelock-Fay, a former world junior champion on the track, laid the foundations for his win with a gutsy ride up Coronet Peak on Thursday and managed to hold on in the last couple of days.
Evans, however, took the limelight on Saturday, taking his first stage win and the first stage win by a Dunedin rider since Greg Henderson won a couple of stages in 2010.
Evans said it was a big thrill for him to win the bunch sprint in the final stage into Queens Park in Invercargill.
''I'm rapt. This has been a dream of mine to get a stage win down there. It is the biggest race of its type in New Zealand,'' he said.
Evans (22) won by more than five bike lengths and was well led out by team-mate Roman van Uden, of Auckland.
It was the culmination of a lot of hard work by Evans in what he said was a tough tour.
''There was a few climbs which probably didn't suit me. I've been waiting for a bunch sprint all week and it finally came along.''
Evans finished 21st on the tour, about the same as last year, and he had no complaints with his placing.
He was looking to join a professional team overseas but for now would be concentrating on training for the national road championships in Christchurch in January.
He would also graduate from the University of Otago next month, with a commerce degree, majoring in management.
Lovelock-Fay was never really under any pressure in the final couple of stages on Saturday.
A 13km time trial started the day and it was won by Joe Cooper, who had won the same stage last year.
Cooper was 21sec ahead of Lovelock-Fay in the time trial and going into the final stage of Winton to Invercargill there was only 41sec between the two riders, both members of the Avanti team.
The final stage was a relative non-event as the team protected Lovelock-Fay's lead.
There were a couple of minor breaks but by the time the finish line came into view the main bunch was intact and it was then left to Evans, of the PowerNet team, to do his magic.
McCormick won the under-23 grade while Matthew Zenovich retained the sprint title.
Thomas Stewart was king of the mountain, while veteran Gordon McCauley claimed the over-40 title.
