A slip is being cleared on Tiniroto Road at Hangaroa Bluffs in July 2022 after one of many severe weather events. This section of road was taken out by the river in Cyclone Gabrielle and rebuilt by a forestry company, but is closed now after a tension crack was identified in the bluffs by geotechnical engineers after heavy rain in June last year.

Coalition Government ministers have approved $3 million for optioneering and geotechnical work to begin the Tiniroto Road rebuild.
During Cyclone Gabrielle, Tiniroto Road was washed out along the Bluffs section and approximately 1400 metres of road was undermined while river protection works were partly or fully destroyed.
The two-lane roadwas scoured away and reduced to less than one lane in parts. Retaining wall structures and rock protection works were compromised or destroyed.
Major bluff slips washed away the road at two locations, with a combined total of 45,000m3 of material washing out the road below and being deposited into the river and on the remaining road.
Existing infrastructure such as retaining walls, culverts and bridges were severely damaged or washed away. The Hangaroa bridge off Tiniroto Road was also washed out.
The money for the works is coming from cyclone recovery funding and Government investment company Crown Infratructure Partners (CIP).
“At this stage the project’s plans are to commence the site investigations and optioneering phase for the Tiniroto Road Project and to engage in consultation and engagement and develop a concept design of the preferred route,” a CIP spokeswoman said. “On completion of this planning work, Gisborne District Council will have greater certainty around total project costs to complete construction, and further funding will be sought.
“The overall project goal is to secure the Tiniroto Road as a main collector road for Gisborne District Council and as an alternative route to the SH2 eastern coast road linking Gisborne and Wairoa.”
