Mr Hamilton will also start partaking in the up coming 10 year plan meetings and public consultations.
Hamilton News asked Mr Hamilton in January what he would bring to the table if elected.
"I want to provide more clarity around the rates process, to build more collaborative partnerships with business and the community — the likes of Momentum and property developers such as garden place so council isn't always picking up the tab for everything and to maintain existing infrastructure and not let maintenance lapse for the sake of budgets appearing better than they are," Mr Hamilton said.
Mr Hamilton's salary as Councillor will be $71,638 per annum.
The byelection came as a result of the passing of councillor Phillip Yeung in late September.
