Road sealing crews have begun working along stretches of SH5 between Napier and Taupo and motorists can expect travel delays up to five minutes.
The work is being carried out at sites between Bay View and Tarawera and temporary speed restrictions have been put in place along with stop/go signalling.
Similar work is being carried out at sites along SH2 north between Napier and Wairoa as well as in the Morere region and speed restrictions and signalling are also in place there.
Motorists using the northern stretch of SH2 will also come upon drain clearing crew at various points, and these too will cause slight delays to travel time.
On SH50 between Kereru and Takapau seal work is being carried out with restrictions in place.
