Workers received both positive and negative feedback from passersby during the installation with no incidents reported to the Police by Spark or its contractor.
Stephen Fookes, representing residents against the tower, was disappointed, saying the "process had not been balanced" and ratepayers had been "disregarded".
He said further action would be taken "principally through the legal regulatory process".
Fookes earlier claimed there were about 120 residents opposed to the tower.
Spark said the new site was permitted activity which would help relieve congestion off the existing towers serving the area.
