"The variable speed signage has been very effective in reducing crashes in other areas of New Zealand, but until this is installed we are taking further steps immediately," Mr Allen said.
Chair of the committee, Cr Dave Macpherson, said a serious crash this week had further highlighted the potential risks and immediate action was being taken to slow cars down as they approach the intersection.
Three men were injured, one critically, after a crash at the intersection on Tuesday. All of the injured were in the same vehicle when it and a ute crashed at the intersection of Thomas and Gordonton Rds about 9.30pm yesterday.
"Drivers are entering the 80km/h Gordonton Rd from a lower-speed, largely residential Thomas Rd and an error in judgement can have serious, and potentially tragic consequences. We've already done safety work at this intersection before new 60km/h electronic variable speed limit signs are installed in mid-October but we need to do more," Cr Macpherson said.
"Councillors have raised concern over this intersection and the council is making immediate changes. These changes and slowing approach speeds are likely to cause some peak-time delays but safety has to come first." he said.
"We urge all road users to take extra care in this area, and as at all our city intersections, we ask drivers to slow down, drive to the conditions and look twice for other vehicles."
