Roading and Infrastructure

Cyclone Gabrielle caused major damage to Tararua’s roading network, with 49 roads closed and many more restricted. Restoring access for isolated communities was one of the biggest priorities of the recovery programme.

$48 million from Waka Kotahi (NZTA) helped not only reinstate our roading network,  but also strengthen roads and bridges to better withstand future events.

The cyclone recovery programme has made strong progress in restoring the district’s roads, with over 2,300 faults completed since initial assessments. Most were low-complexity issues like slips, culvert blockages, and pavement repairs, but good progress has also been made on more technical challenges.

  • Faults resolved: 1,871 low, 376 medium, 55 high.
  • Remaining faults: 99 still open.
  • Key achievements:
    • 1,097 slips cleared.
    • 459 drainage issues and 163 culvert blockages fixed.
    • 268 dropout repairs completed (50 still underway).
    • Additional work included tree removal, pavement repairs, and wall reinstatements.

The work has not only repaired cyclone damage but also improved resilience, with stronger drainage and slope protection in many areas. This progress has reconnected communities, reopened key routes, and supported local wellbeing and economic recovery.

Key roading projects included:

Marainanga Gorge - Coast Road

The reopening of Marainanga Gorge Road was a major milestone in recovery from Cyclone Gabrielle. Around 300 m of the road had been washed away, requiring a full rebuild raised 10 m higher for resilience. Despite winter and river challenges, strong collaboration between Council, Horizons Regional Council, iwi partners, and local contractors restored access for residents, farmers, and businesses. The project not only reconnected communities but also reinforced long-term safety and resilience.

Rakaiatai Bridge

Cyclone Gabrielle washed away the Rakiatai Bridge, cutting off the only all-weather route for residents. Council quickly installed a temporary pedestrian bridge using recycled beams, restoring access for residents to schools, medical visits, and farm work. A permanent replacement, with raised abutments and reinforced foundations, began construction in October 2024. Interim access routes ensured farming and emergency services continued. Collaboration with contractors and local farmers helped adapt plans to site conditions and community needs, restoring this vital crossing efficiently.

River Road

The main access road to Akitio Beach was severely damaged, with over 300 metres washed out and the road closed for two months, cutting off residents and services. Restoring access became the top priority, with a temporary route reopened along the old alignment through private property in collaboration with landowners and contractors. This interim solution reconnected the community while long-term repair options were considered. Once access was secured, focus shifted to addressing wider damage in the area, including Marainanga Gorge.
