Motorists using the northern stretch of State Highway 2 between Napier and Wairoa can expect to encounter delays over the following week as repair work, slip clearance and construction projects take place.
Contractors have moved into the area called Hippies Curve near Lake Tutira to construct a new culvert and temporary speed restrictions as well as stop-go signalling will be in place.
Similar safety measures are also in place at sites between the Devil's Elbow and Wairoa where clean-up work from slips is continuing, as well as between Wairoa and Morere for general surface repair work.
New Zealand Transport Agency spokesman Oliver Postings said heavy loaders and trucks would be operating at the slip clearance sites and drivers needed to be cautious.
Power pole work is continuing on stretches of SH50 with a replacement programme under way from Omahu Rd to Roy's Hill.
