NZ Transport Agency Waka Kotahi (NZTA) is advising that emergency road repairs are underway at the intersection of SH1 and SH29 in Piarere following heavy rain.
The roundabout opened to traffic on Tuesday 24 September with two temporary approaches in place.
The surface of these approaches has deteriorated as a result of recent weather, requiring urgent repairs.
More intensive repairs will be carried out tonight, from 7pm until 12am, with stop/go traffic management in place.
NZTA thanks road users for their patience and asks people to adhere to the signage and take extra care when travelling through the area.
