His second was pure class. He faked a free kick from the centre circle before having the ball slipped into his path and going on his way. A jinking run took him past multiple defenders to the edge of the area, where his curling right-foot shot found a home in the righthand corner of Claudelands' net.
His third came towards the end of the half from the right side of the box. He faked a pair of shots before chopping on to his right foot and beating the goalkeeper from an acute angle.
The improving Josh Nelson scored a brace in the second half to go with Cooper's fourth, putting an exclamation mark on the Blues' campaign.
His first was magic - a first-time volley from outside the box that looked good from the moment it left his boot.
All that left time for was for a few players to attempt to pick up their first goal of the season.
Will Clague went close twice - once in causing a deflection that led to Cooper's fourth and the other time in following up a penalty he won that Sam Nahna failed to convert.
Blues coach Duncan Lowry was beaming following a home campaign in which his side scored 46 goals and conceded only four.
"It was nice to go in at halftime at 3-0 up. It took the pressure off us and it was party time from the second half in," he said. He added that the players had gelled with the fortnightly travel to Auckland.
Tauranga City United 6 (Andrew Cooper 4, Josh Nelson 2) Claudelands Rovers 0.
