The slip, which followed days of heavy rain in the area, shut the main road north out of Taranaki.
Travellers wanting to get to the region have been diverting through State Highway 1 to Whanganui while the Transport Agency cleared the road.
The detour added an extra three and a half hours to the journey.
Road Transport Association spokesman Tom Cloke earlier said it was costing truckies between $1000 and $1500 more to take the longer route.
The Transport Agency said the road, south of Mokau, was now re-opened.
The nearby SH43, which was also reduced to one lane by slips over the past few days, was also now fully open, said NZTA.
