The northern stretch of SH2 is a landscape of roadworks and safety upgrades and travellers can expect delays between Napier and Morere.
Road surface repair crews are at work between Putorino and Tutira and the Morere region with temporary speed limits and stop-go signalling in place.
A New Zealand Transport Agency spokesman said the impacts on travel time could be up to five minutes.
Guardrail work at sites between Nuhaka and Wairoa will also create some slight delays with similar restrictions in place.
Surface water blasting work is also being carried out on the stretch from Tutira to Tangoio.
