North of Tutira at Sandy Creek there are traffic lights and speed restrictions in place due to the highway being reduced to one lane by a dropout which occurred after last month's heavy rainstorms.
Road repair teams are also working between White Pine Bush and Tangoio and temporary speed restrictions are in place.
Contractors will also be installing new sections of guardrail on Waikoau Hill with stop-go signalling in place at times.
On SH2 south of Hastings work is continuing on NZTA's safety improvements programme with seal widening work in the Te Hauke and Te Aute areas.
Temporary speed limits and stop-go signalling are in place and there will be slight delays in travel time.
Similar restrictions have been set up at several sites on SH5 where slip clearance work continues to be carried out.
Slip clearance work is also continuing at sites between Ardkeen to Lake Waikaremoana on SH38 with speed restrictions in place.
