Crews are also working on drainage maintenance at sites between Tangoio and Putorino.
Similar work is being carried out on SH2 south at sites between Paki Paki and Waipawa where speed restrictions are also in place, as well as on SH5 between Napier and Taupo at various sites from Eskdale to Tarawera.
Motorists using the Hawke's Bay Expressway between Westshore and Longlands Rd can also expect to come across slow-moving road-marking vehicles although the NZTA said delays on the stretch would be "negligible".
At the region's two major roadworks sites speed restrictions are in place but delays are expected to be minimal.
A new road layout is now operating at the intersection of the SH2 expressway stretch and Watchman Rd, while restrictions are in place at the Whakatu Arterial site at Mangateretere.
