The win is their third domestic title after holding it for two consectutive seasons in 1996 and 1997, and was achieved with two games in hand.
It also marks the first time a Southern-based side has qualified for the premier regional club competition in Fiji football history.
Lending a helping hand were 2014 OFC Champions League semi-finalists Ba, who saw their long-running reign on the league end after a shock 2-0 loss to Labasa.
After their sudden exit from the Battle of the Giants at the hands of Rewa last month, Suva were on the hunt for some on-field revenge in their league match at Ratu Cakobau Park in Nausori.
Leone Damudamu put the capital-based side ahead in the 16th minute after nodding the ball in from a corner kick.
Without the services of key players like Simione Tamanisau, Simione Maikali and Epeli Saukuru it was a tough outing for Rewa but they managed to restrict their opponent to just a 1-0 lead going into the break.
Former Labasa man Misaele Braunibaka brought Rewa back in line with their opponent through a 50th minute equaliser.
However two errors from goalkeeper Benito Waqavou ultimately proved costly for the Rewa side.
A powerful shot from Shahil Dave from the right edge of the Rewa box slipped from Waqavou’s grasp and over the goal line to return Suva’s lead.
A similar error on Suva striker Ravinesh Karan Singh’s effort added salt to the wound as Waqavou could only watch the ball roll into his net.
Suva coach Gurjit Singh was delighted by his team’s achievement.
“It was a good achievement for the team not only to secure our spot in the Champions League but also win the National League,” Singh says.
While Suva will be making their debut in the Champions League, long-time participants Ba are not yet out of the running.
Ba, Nadi and Labasa are still in contention to finish runners-up in the league, with Fiji’s second Champions League berth still up for grabs.
