Track reinstatement options

Over the last few months, we’ve been gathering and analysing information we need to inform the possible options to reinstate walking access to Cathedral Cove.

We’ve examined long-term and short-term options – work guided by the legislation we operate within, the values and cultural heritage of Ngāti Hei, as well as what can be practically achieved at the site.

We need to balance the impact of visitor tourism, the economic value of that tourism, the costs and benefits of the options, and the likely impact of climate change at a coastal site where land movement has been an issue for some time.

Our team has produced a presentation which explains our context and the options we’re exploring.

Sharing this information is part of our wider engagement work with the Coromandel community – work which continues over the coming weeks.

5 April 2024 update

DOC is working on a durable solution for opening walking access to Mautohe Cathedral Cove. This is a landscape that’s vulnerable to landslides and rockfalls. Our goal is to reopen the track safely, in a pragmatic way. 

The Tonkin + Taylor 2023 report undertook mapping and a landslide risk assessment following DOC’s Natural Hazard Risk Analysis methodology. The report recommended DOC review the site and explore practical risk reduction options. 

This review process is underway and includes: 

1. Landslide predictive modelling – this shows how resilient the land is likely to be in the future.
2. Geotechnical monitoring to ascertain if the land has stabilised and what level of risk remains. We had to wait to let the land settle after an extremely wet year in 2023. Now we can proceed to test what has changed further.
3. Identifying options for a resilient walking track access to Mautohe Cathedral Cove beach.
4. Identifying practical visitor risk mitigations.

What we’ve done this year 

• In February, DOC, with Ngāti Hei’s support, undertook a summer visitor experience survey. Analysis of the visitor experience survey responses are available below.
• In March, DOC, Ngāti Hei and technical experts visited the site to assess access and infrastructure options. Further investigations are required by technical experts.
• In March, we commissioned a new landslide predictive model to be run for Mautohe Cathedral Cove. This showed a high likelihood of further landslides under different storm conditions.
• Community engagement is underway with support from Ngāti Hei, Thames-Coromandel District Council and Destination Hauraki Coromandel. Follow our website for more details. 

Still to come 

• Results of the geotechnical monitoring are due June 2024. 
• Feasibility assessment of options for resilient walking access are due to the Minister June 2024.

2024 Visitor survey results show high levels of satisfaction

2024 visitor survey results show highest level of overall visitor satisfaction with Mautohe Cathedral Cove in the country.

This summer, with the support of Ngāti Hei, DOC undertook a visitor experience survey to test visitor perceptions of their visit to Mautohe Cathedral Cove via beach access. The survey was conducted from 27 January to 29 February 2024. It collected the impressions of visitors who used marine operators to access the Mautohe Cathedral Cove beach.  

The survey used the ‘intercept method’ for recruiting participants, approaching randomly selected visitors when they arrived back from the Cove to answer questionnaires. A total of 210 questionnaires were completed, which is above the minimum sample size required to provide statistically robust findings. 

Survey results indicate: 

• Mautohe Cathedral Cove remains a top New Zealand visitor destination- despite the track closure
• the overall satisfaction with the Mautohe Cathedral Cove experience is the highest for any DOC managed destination in the country
• how people access the Cove – currently only by boat or kayak - doesn’t influence their satisfaction rating
• scenery and landscapes are the drawcard for visitors to Cathedral Cove.  

The survey also assessed facilities and services for visiting Mautohe Cathedral Cove with the frequency of water transport scoring highly (3.9 out of a possible maximum 4), followed by safety information and structures (3.7 out of 4).

Community information sessions are underway  

We are engaging partners, stakeholders and the community to help inform the most compelling solution for Mautohe Cathedral Cove - one that people can support, now and into the future.

Over the next few months, we are running: 

• stakeholder update sessions
• a community survey 
• community drop-in sessions. 

We’re working closely with Ngāti Hei and proactively engaging with identified key stakeholders before seeking wider community feedback.  

We are committed to working collaboratively with Thames-Coromandel District Council and Destination Hauraki Coromandel to maximise opportunities for the community to participate.  

We’ll update this page when we have more information to share. 

Timeline 

The future approach and timeline are subject to change as options are tested, and engagement is undertaken.

January 2024 update

We’re now able to share an overview of our work programme for Cathedral Cove.

There are a range of complex overlapping issues we need to work through to find a safe and sustainable solution at this location.

Background

Weather impacts from Cyclone Hale, Auckland Anniversary weekend flooding and Cyclone Gabrielle in early 2023 caused significant damage to the Cathedral Cove track. The track was closed because of the damage and safety risks of land instability land and extreme weather.  

Five rockfalls occurred on or around the Cathedral Cove Arch between August and November 2023, during a variety of weather conditions.

The track is in a Recreation Reserve in Hahei. There are several laws guiding the management of the reserve.  It is next to the Te Whanganui-o-Hei Marine Reserve, and the Arch itself sits within the marine reserve.

Before the COVID-19 pandemic, the track was used by about 250,000 visitors a year, 75 percent are international. The typical visitor to Cathedral Cove is low skilled at dealing with natural hazards. So, we manage this type of site closely to reduce exposure to risk from natural hazards compared to other tracks that don’t have this type of visitor.

In 2020 GNS Science developed a Natural Hazard Risk Assessment methodology for DOC to assess natural hazard risks for visitors using DOC facilities and to inform mitigations.  This methodology was used by consultancy firm Tonkin + Taylor to carry out an independent assessment of the landslide risk at Cathedral Cove on behalf of DOC.

What we know

Landslides and rockfalls have long been an issue for Cathedral Cove.  The weather in January and February 2023 caused many of these to activate.

After the cyclone, DOC staff did initial safety assessments.  This was followed by site visits by geotechnical experts from Tonkin + Taylor to understand the level of landslide risks to visitors.

Between March and July 2023, Tonkin + Taylor did a landslide risk assessment. They looked at the tracks from Hahei Beach to Grange Rd carpark, Cathedral Cove Beach, Stingray Bay, and Gemstone Bay.

The risk assessments have been done at a site-wide scale.

The greatest level of risk is for visitors using the whole site (both the tracks and beaches) as they are exposed to all landslide hazard areas. The longer a visitor stays at Cathedral Cove, the higher risk they are exposed to.

The tracks and structures are damaged, and the greatest concern is the ongoing instability of land.

Tonkin + Taylor and DOC concluded:

• The risk is at the high end of DOC’s acceptable threshold for a site like this, and for the typical visitor and numbers using it. Before reopening the track, mitigations are necessary to reduce the risk to visitors from landslide hazards.
• Several areas are assessed as hazardous with limited practical or effective mitigations possible. These areas are beach cliffs at Stingray Bay, parts of Cathedral Cove Bay, the rock arch itself, and the track from Hahei to Grange Road carpark.
• Reducing visitor numbers during and after rainfall events would reduce potential for harm to visitors from landslide hazard, however this is very difficult to practically implement.
• DOC staff are exposed to the highest level of risk from landslide hazards when they work at these locations. Reduced time onsite mitigates this – an approach already being taken.
• Overall, this track is categorised as one that should not be re-opened to the public without reducing the risks. Given the typical type of the visitor, DOC needs to reduce risk to as low a level as reasonably practicable and allow visitors to make informed risk decisions about visiting the site. Any solutions also need to be cost-effective and resilient.
• Currently, and when compared to other similar sites DOC manages, visitors to Cathedral Cove are exposed to a higher level of risk of serious injury or death.
• Based on these safety elements DOC decided the Cathedral Cove track could not open for summer 2023/24.

The options

A range of concepts to re-route the track have been outlined by Tonkin + Taylor.  Ideas from community groups have also been received.

Re-routing the track will not be undertaken until there is confidence the preferred route will reduce the level of risk to as low a level as reasonably practicable. This confidence can only be gained from monitoring proposed routes.

Other tools to manage the level of risk to visitors could be considered– e.g., guiding, controlled access, alternative structures.

Effective and clear communication of risk to visitors prior and as part of their visit will be important and has been implemented at place and online.

Any mitigation approach must be in line with legislation, recognition of cultural values (including meeting Treaty Settlement commitments to Ngāti Hei) acceptable cost, and risk.

What we’ve been working on

A minimum monitoring period of six months has been recommended before remedial work is undertaken.  This monitoring will start in January 2024. It will include physical surveying and specific sites will be monitored for land movement by Tonkin + Taylor. The goal is to better understand landslide and rockfall frequency, and to identify land areas where we could reroute the track on.

While monitoring work is done, DOC has taken action to:

• Work with Ngāti Hei on lifting a rahui to enable marine access for a viewing experience of the arch and short-stay beach landings.
• Work with commercial operators, emergency services, councils to emphasize safety in the marine experience.
• Deliver three alternative walking/sightseeing experiences in the area to provide opportunities for visitors, community, and businesses to use.
• Introduce at-place Tiaki Rangers, employed by DOC and Ngāti Hei, to share safety messages and information on alternative experiences in Coromandel.

What next

1. January 2024: A high-level review will start to shortlist options to reduce the visitor safety risk to an appropriate level for visitors to walk to Cathedral Cove.
2. February – April 2024: Preferred options will be developed with Ngāti Hei and in consultation with the wider community. A visitor survey will be undertaken in February to understand visitors’ expectations.
3. June 2024: We will have the information from the land stability monitoring.
4. June – August 2024: Options will be assessed against the stability information, legislative, strategic, cost benefit and risk requirements. This will include stakeholder and community communication and engagement.
5. September 2024: A decision will be made on re-routing the track or developing an alternative option. This will be communicated widely so community and businesses can leverage opportunities.
6. A business case will be finalised to confirm the delivery plan and resources needed to be successful. Timing for implementing the preferred option will depend on the complexity of the solution chosen.
7. Communication will continue throughout 2024 through proactive information sharing on our website, via media, and relevant channels.  

The forward approach and timeline are subject to change as options are tested, and engagement is undertaken.

Cathedral Cove visitor experience — Summer 2023-24

Map of tracks for Summer 2023-24.
Image: DOC

• Alternative visitor experiences have been created near Cathedral Cove to ensure visitors to Coromandel can experience the beauty of the coastline. These have been enabled by collective work of DOC, Ngāti Hei and operators.
• Visitors are encouraged to explore other beaches and walks around the Mercury Bay area.  
• The experiences are aimed at day trip visitors – the same type of visitor who would normally use the walk down the cove.
• The work done includes improvements to existing tracks, and new routes to sites considered culturally significant to local iwi. This provides the added benefit of providing cultural stories to enrich the visitor experience.
• The cultural heritage sites are historic pa – Hereheretaura and Te Pare - used by Ngati Hei during their long presence in the area.
• Hereheretaura and Te Pare were defensive pa used by Ngati Hei during their conflicts with other iwi in pre-colonial times.
• DOC has employed Tiaki Rangers who will caution visitors on the ongoing safety risk around Cathedral Cove and share information on other locations where people can enjoy a coastal walking experience.
• The Tiaki Rangers will also share Ngāti Hei cultural stories about the area.
• Grange Rd in Hahei will give sweeping views across the Mercury Islands and Te Whanganui-o-Hei Marine Reserve.
• Grange Rd will be a drop-off only location – there will be no short, medium, or long-term vehicle parking.
• Pedestrians can walk up to the Grange Rd lookout point. Seating and picnic areas have been created.
• Work has also been completed to add a loop track to McHand’s Lookout. The loop track crosses private property, and connects to Lees Road and DOC land to the north of Cathedral Cove. This look-out – also giving expansive views over Mercury Bay - forms part of a 90-minute walk from the Lees Rd carpark. 
• For this summer Cathedral Cove itself will be a marine-based experience, with several commercial operators offering services which include brief stays on the beach.
• International marketing of Cathedral Cove is portraying the marine-based experience.
• DOC and Ngāti Hei continue to urge people not to use the walking track down to Cathedral Cove – it is not safe and will not be reinstated for summer 2023-24. Barriers will be in place to prevent access and visitors should not progress past them. Geotechnical experts have identified use of the track presents a high risk compared to other similar locations DOC manages.
• Rescuing an injured person from Cathedral Cove puts others at risk and is not straightforward based on advice from emergency services.

We have confirmed our timetable for our work on Cathedral Cove over the next 18 months, including:

• plans for management of the site this summer
• our consideration of options
• when we expect to carry out community and stakeholder engagement.

Cathedral Cove recovery timeline (PDF, 229K) outlines the timeframes. These are indicative/estimated and our work is subject to a range of contingencies.

Landslide risk assessment report

We commissioned an independent landslide risk assessment from Tonkin + Taylor for Cathedral Cove and the area around it. 

Our Visitor Safety staff reviewed the Tonkin + Taylor report within DOC’s visitor safety framework, which factors in the level of risk acceptable for different kinds of visitors.

• Tonkin + Taylor risk assessment report (PDF, 16,363K)
• DOC’s visitor risk response to the Tonkin + Taylor report (PDF, 723K)

There is an increased risk of injury or fatality at this site, from rockfall and landslides.

We strongly urge visitors to stay ten metres away from the cliffs, and not to stand or walk under the cove’s arch, where sporadic rockfall can occur. We also advise visitors avoid the beach during or after heavy rain. The risk of rockfalls and landslides is highest at these times, however, rockfalls and landslides can also occur in good weather

If you are concerned about the risk, do not visit the area.

Tonkin + Taylor’s report, and our review of it, has informed a decision to not reinstate tracks to Cathedral Cove for summer 2023-24.

Access to Cathedral Cove is from the sea, only. Visitors should not use the tracks.

Visitors should not enter the arch on Cathedral Cove beach. 

The toilet at Cathedral Cove has also been decommissioned and is unavailable for use.

Next steps

We have started a project to reimagine the wider Hahei visitor and conservation experience and site. This will include an exploration of options and engagement with stakeholders and the community.

This page will be updated by the project team as new information is available, proposals are formed, and decisions are made.
