Conditions were miserable at the Caledonian ground but the mood was festive on the red-and-white side of Otago football as Caversham completely dominated its old rival.
With the rain-soaked turf holding the ball up and making dribbling impossible, Caversham pursued an aerial attack that paid dividends, scoring two goals in the first half to take control of the game.
The Tonga Park-based club is into the quarterfinals of the Chatham Cup and expects to find out today if it has a home game and against which side.
Long-serving coach Steve Fleming said the wet ground and constant drizzle had forced Caversham to play sensibly.
"We didn't want to be particularly fancy," Fleming said.
"The key was putting good balls into the air and giving our strikers a chance to get on to them.
The fact that we got three goals from crosses shows that was a pretty good plan.
"There were certainly another couple of good chances that, possibly, we should have done better with, but I can't complain."
Fleming said a key to Caversham's attack was the balanced load it placed on strikers Dugdale and Tom Jackson, and the midfielders behind.
Dunedin Technical, in contrast, relies heavily on the prolific scoring rate of deadly marksman Aaron Burgess, who missed the Cup fixture.
"I certainly think we've got a broad base of scorers and that creates a problem for any defence because they can't overload the marking on any one player," Fleming said.
Dugdale was all-action at the head of the Caversham attack, hustling and harrying, as he was given plenty of ball and space to move.
Jackson was industrious beside him, while Robbie Deeley controlled the middle of the park and Blair Duncan gave good service from the left.
Caversham dominated possession and it did not waste a single ball, pushing forward with purpose and delivering crosses and corners with impressive accuracy under the conditions.
Dunedin Technical had the first scoring chance, with Riki Chidley angling in a low ball that Alistair Rickerby just could not reach.
But Caversham replied immediately.
It appeared Dugdale had glanced the ball into the net from a cross but Fleming said it was credited as an own goal.
There was no doubt about the second goal.
A Caversham cross took a nasty deflection off a Technical defender and Dugdale was waiting to bury the ball in the net.
Caversham looked far more aggressive at this point and had two more good chances in the half, with Patrick Fleming trying an ambitious curling shot from long range and Jackson heading on to the crossbar.
Rickerby and Justin Flaws were trying hard for Technical but Flaws should have done better with a scuffed shot near the end of the half.
The second spell was rather flat, highlighted only by a Jackson goal on the end of a nice pass from Mike Smith, and two great chances for Dugdale.
In the key premier league game, Roslyn-Wakari captain Ben Keat scored a hat trick in his side's 5-3 win against Mosgiel.
Green Island beat Grants Braes 3-0 and Northern beat Queenstown 2-0.
University, depleted thanks to holidays and the flu, defaulted to the Southern Spirit.
Caversham 3 (Dave Dugdale, Tom Jackson, own goal), Dunedin Technical 0.
Half-time: Caversham 2-0.
