Hoffman, who had been out of the game for nearly two years, showed the time away had not dented the skill or power that had previously earned him selection in the New Zealand reserve squad.
He beat Peter McMillan (Southland) 21-12, 21-7 in one semifinal, while promising Canterbury player Asher Richardson beat Otago's Mathew Ng 13-21, 21-12, 21-19 in the other.
The two form players of the tournament were pitted together in what was expected to be a classic final.
Richardson made a good start, forcing Hoffman into some uncharacteristic errors and winning the first set 21-14.
Hoffman altered his game plan and used a change of pace to upset the rhythm of his younger opponent.
Another key feature was Hoffman's electing to attack the body of his opposition, cutting down on the angles Richardson had available to him.
These tactical changes proved decisive, with Hoffman taking control to secure a 14-21, 21-13, 21-11 victory.
Hoffman, in arguably his strongest discipline, then combined with Canterbury representative Ella Veluta-Dick to dominate the mixed doubles competition, winning the title without conceding a set.
Hoffman's bid for the full set of titles was nearly derailed when his doubles partner, Otago representative Eddie Taylor, had to withdraw from the tournament after badly damaging his knee.
A makeshift combination of former Otago representative Roger Southby and Hoffman did not drop a set in to strongly win take doubles title.
Otago's Elaine Rose regained some of the form that had been missing in the past season or two, beating Rebecca Jury (Canterbury) 21-13, 19-21, 21-16 in the women's singles final.
Rose and Angela Wright reached the final of the women's doubles.
While the seniors were dominating the court in Dunedin, the Otago juniors were collecting titles at the Southland under-15 and under-19 championships.
Mitchell Wilson and Jessica Thompson won all three under-15 titles, combining with and then defeating other Otago players in the finals of the singles, doubles and mixed doubles.
Mitchell won the doubles with Daniel Cleminson and mixed with Jessica.
The girls' doubles was won by Jessica and Brittany Reddington.
In the under-19 tournament, Otago under-17 player Luke White won the singles, beating Cameron Thompson, and was runner-up in the doubles with Ben Sparrow (Otago) to James Swan (Otago) and Richie Sharma (Southland).
