Second-placed Caversham, on Chatham Cup duty, has three catch-up matches to make up the difference.
Technical scoring machine Aaron Burgess turned on an astonishing half-hour blitzkrieg on the Rovers' goal when he netted five times in a frenetic spell before halftime.
Burgess displayed his full repertoire of clinical finishing skills as he climbed to the top of the Golden Boot ladder and just missed equalling his personal record of six goals after hitting the Rovers woodwork three times in the second half.
A strong run by Technical midfield general Andy Coburn set up the first goal in the 18th minute, with an intuitive cross meeting its target and Burgess finished with the precision of a German engineer as the ball nestled in the corner of the net past outstretched Rovers keeper Steve Henderson.
Technical's confidence grew after the initial goal, with right midfielder Michael Flaws and Coburn continuing the delivery of quality ball into the attacking zone which Burgess gratefully accepted.
The hesitant Queenstown defence looked more leaden-footed by the minute as several offside claims were declined by the match officials.
Both teams went to halftime double-checking the unlikely 6-2 scoreline, which included two quality strikes from Queenstown's Oded Nathan.
Greens Island's recent good form continuedwith a 2-1 win over University.
A close-range Dan Rutter header opened Island's account, before Luke Macris converted a penalty for University.
