With the float procession starting around midday tomorrow, road closures will commence from 11.30am onwards between Avatiu Harbour and Avarua Harbour roundabout, near the Court House.
Police said motorists can expect road diversions between these two areas. They will put cones and detour signs on the road and all vehicles in town will be diverted to the back road near Pickering Motors.
Police spokesman Trevor Pitt said police were finalising the personnel required for the festival and its events.
“Police will be maintaining a presence at all points of traffic diversions, this is a standard operational measure taken every year during the Constitution celebrations and residents will be accustomed to such steps, which are necessary to ensure complete safety throughout the town area,” he said.
He advised that, to avoid the congested areas if possible, people must get to their town activities and requirements earlier if they can. Police say they are also looking at strategies to ensure the safety of the public and visitors as well. The public is asked to cooperate with Police and event organisers.
