Report emphasises risks of rockfall, landslides
at Cathedral Cove, Hahei
An independent report confirms the risk of potentially harmful rockfall and
landslides at Coromandel’s Cathedral Cove and its adjacent bays and tracks.
After extreme weather events in January and February caused landslips and
rockfalls – and damaged tracks to the point some are impassable – the
Department of Conservation has urged people to stay away from Cathedral
Cove and nearby bays, and the network of tracks connecting them.
Following those weather events, DOC commissioned Tonkin + Taylor (T+T) to
produce a landslide risk assessment report for the area. DOC also requested
the report include options for mitigation of track damage.
T+T’s report is the result of several site visits by the company’s specialists.
The report highlights the need for practical risk reduction strategies at the site.
DOC Hauraki-Waikato-Taranaki Regional Director Tinaka Mearns says DOC’s
internal review of the T+T report, when set against DOC’s own visitor safety
framework and measures, has determined an increased risk of injury or
fatality at the location.
“The report details ongoing risk of landslide across the wider site,” Tinaka
“Across the 3.8km of tracks around Cathedral Cove and the adjacent bays,
180 historical or recent landslides were identified. Beach cliffs, including those
overlooking Cathedral Cove were described as ‘particularly hazardous’ due to
ongoing landslides and rockfall.”
Landslides washed away sections of the main track down to Cathedral Cove,
and the report signals more of the same kind of damage could emerge.
DOC’s Visitor Safety Team has determined the associated risk is at the top
end of the scale DOC can manage for the type of day-trip visitors who have
traditionally visited Cathedral Cove.
With the main track to Cathedral Cove extensively damaged and at risk of
further instability – and no “quick fixes” available for other tracks compromised
tracks in the area – DOC will not reinstate the current walking routes down to
the beach for this summer.
Visitors are also strongly urged not to go through the cove’s famous arch, with
debris falling from the arch to the sand below as recently as last weekend
However, within the next few weeks visitors will be able to return to the beach
via the Te Whanganui-A-Hei Marine Reserve.
“Renewing access to Cathedral Cove from the sea allows people to go there –
but we want to make very clear there is still risk associated with going to this
site and people need to inform themselves properly before visiting,” Tinaka
“There is still potential for rockfall landslides at these sites, and we need to
emphasise this to the public. You go at your own risk.”
DOC will also decommission the toilet block at Cathedral Cove beach. Visitor
numbers to Cathedral Cove will be monitored by DOC’s Coromandel District
“We need to make sensible long-term investments at this site, rather than
spend money on short-term solutions which are not sustainable and will not
withstand the increasing extreme weather events caused by climate change,”
Tinaka Mearns says.
Ngāti Hei, the local iwi to which Cathedral Cove is a significant site, will lift its
rāhui over the area, in place to protect visitor safety since last summer’s
extreme weather events.
Today’s announcement comes during Conservation Week, which encourages
people to ‘take action for nature’.
“We’re making this announcement during Conservation Week because we are
taking action for nature by developing a longer-term sustainable plan for this
site,” Tinaka Mearns says.
“We want to work with stakeholders and iwi to reimagine the wider Hahei area
and experience, so it is safe, enjoyable and is in line with our conservation
goals and strategies. We’ve contracted an experienced project manager to
commence work on a plan to reimagine the Hahei conservation experience –
a project which will include community consultation on future options.”
DOC has updated website information on Cathedral Cove on its website,
including making the T+T report publicly available.
Cathedral Cove is an iconic visitor destination, famous for its idyllic coastal
location and natural archway. It has historically received up to 250,000 visitors
The site is managed by DOC with support from Ngāti Hei, the local iwi.
Extreme weather events in January and February 2023 – including Cyclone
Gabrielle – caused storm surge, landslides, erosion and rockfall at Cathedral
The damage to tracks, stairs and natural features like cliff faces and slopes
People have still been able to visit Te Whanganui-a-Hei Marine Reserve,
adjacent to Cathedral Cove but were asked not to land on the beach.
