Marlborough Sounds Future Access Study

Stock Many of the Sounds roads were originally built as local access tracks and were never designed for today’s transport loads and damaging weather events. Unfortunately, more of the storms that have undermined these vulnerable roads in 2021 and 2022 are possible in the future.

Council embarked on the study to support the case for funding safe and resilient long-term access solutions for the Sounds, both for itself and to obtain funding assistance from Waka Kotahi.

Consulting, engineering and construction company Stantec led the Marlborough Sounds Future Access Study team. The Waka Kotahi business case process guided the study.

The study looked at five geographical areas, recognising their own distinct access issues.

Rai Valley to Te Aumiti / French Pass. Ronga Road (Rai Valley), Tennyson Inlet, Croisilles-French Pass Road, Te Towaka-Port Ligar Road, Bulwer Road, including Rangitoto ki te Tonga / d'Urville Island and surrounding areas.

Te Hoiere / Pelorus. Kaiuma Bay Road including Daltons Road / Track and Te Hoiere Road and surrounding areas – Linked to Te Hoiere/Pelorus Catchment linking back to Te Hoiere/Pelorus River.

Kenepuru. including Kenepuru Road and the outer Sounds

Queen Charlotte Drive , including Anakiwa Road. (Havelock to Picton)

Te Whanganui / Port Underwood. Te Whanganui / Port Underwood and Tumbledown Bay roads (to Rārangi campground)

Marlborough Sounds Future Access Study Boundaries

During 2023, a number of options were considered for the above areas. Following an evaluation process, an ‘emerging preferred option’ and a ‘hazard adaptation pathway' for each of the areas were provided to the public for feedback. This feedback was considered for the final programme business case on the Marlborough Sounds future access.

Emerging preferred options

The Marlborough Sounds Future Access Study took into account the results of community feedback from January-February 2023, the multi-criteria assessment (MCA), cost estimates, the Sounds’ geology, and economic assessments. Based on these results, and input from Council, the study identified an emerging preferred option for each of the five study areas.

Hazard adaptation pathways

In addition to the emerging preferred options, Government required Council to also identify pathways that recognise the future risks of significant events such as storms, earthquakes and sea level rise. These pathways deliver the lowest level of service Council is willing to provide, while still delivering safe transport solutions and access in and out of the Sounds. These are referred to as ‘hazard adaptation pathways.’

Following the second phase of public engagement in June-July 2023, the project team finalised a programme business case to support the funding plan for a safe and resilient transport system for the Marlborough Sounds. The business case was sent to NZTA Waka Kotahi for consideration for financial assistance.

Marlborough Sounds Future Access Study Programme Business Case

Council reviewed and endorsed the final programme business case on 3 October 2023. Resolutions from the Assets & Services Committee were adopted at an Extraordinary Council meeting on 10 October and provided to NZTA Waka Kotahi for consideration.

NZTA Waka Kotahi endorsed the Programme Business Case in December 2023 and indicated what financial support they may provide.

Council will consult the whole of Marlborough on levels of service and rating options via the Long-Term Plan process in 2024.

Final levels of service and funding decisions will be made in June 2024. Once those decisions are made funding applications to NZTA Waka Kotahi will be made and if approved final works’ design can be procured and completed. The construction programme could then get underway at the end of 2024 in some areas.

Some low cost/low risk works are expected to be taking place in early 2024.
