An arch tunnelled clean through a New Zealand headland of eight-million-year-old volcanic ash, joining two beaches, with a no-take marine reserve in the water below.

September·Edge of season

Sep–Nov

Spring warms slowly — the sea climbs from about 15°C in September to 17°C by November as the pōhutukawa set their buds. Crowds are thin, weather closures grow less likely, and the boats and shuttle run in shoulder-season calm before December's rush.

Year-round The arch, Te Hoho and the reserve's snapper, red moki and crayfish are here every day; the bloom, the warm sea, the crowds and the winter storm closures come and go with the season.

Mautohe Cathedral Cove is an arch tunnelled clean through a headland, big enough to walk through, joining the sand of Mares Leg Cove to the smaller beach the cove is named for. You go from shadow into glare in a dozen steps, and out the far side onto white sand and green shallows. Just beyond stands Te Hoho, a rock stack pinched at the waist and crowned with pōhutukawa trees. The water is a no-take marine reserve: Te Whanganui-o-Hei, New Zealand's sixth, declared in 1992. With fishing banned, snapper, red moki and crayfish came back to the rocks below, so a mask is worth as much here as a camera. The white cliff the arch runs through is volcanic ash: ignimbrite, welded together by explosive eruptions around eight million years ago, soft enough for the waves to hollow out and firm enough to stand while they do. The softness that carved the arch is also unmaking it. In August 2023 about two cubic metres of rock dropped out from beneath it, littering the sand with blocks the size of a picnic cooler. Six months earlier Cyclone Gabrielle had cut some 180 slips into the clifftop track and shut the walk for nearly two years. Access returned in December 2024, a storm closed it again in January 2026, and it reopened days later. The cove is open now, but closures can come at any time and the rules keep changing. The tide runs the rest. At low water you cross beneath the arch dry-footed; at high water the sea takes the passage back and the beach thins to a strip. For Ngāti Hei, who have held this coast for generations, the bay carries the name of an ancestor who came ashore from the Te Arawa canoe.

Worth knowing

Good to know

There is no parking at the trailhead — leave the car at the free Hahei visitor car park and take the park-and-ride shuttle, or add a thirty-minute uphill walk up Grange Road.
Don't stop under the arch — DOC asks visitors not to linger beneath it or against the cliffs, and closes the track outright whenever an orange or red weather warning is issued for Hahei.
The cove faces the sunrise — first light comes off the sea and onto the white rock, and you get the arch to yourself; the boats and shuttle loads start arriving mid-morning.
A rising tide can strand you — the beaches are unpatrolled and rips run offshore, so if you cross to the far side, come back through the passage before the water reclaims it.

Things to do

1
Walk through the arch to the far beach
The passage is a tunnel of volcanic ash, high enough to feel like a nave: the noise of the surf doubles under the ceiling, and the far end is pure glare until your eyes adjust. Two beaches, two moods — broad, busy Mares Leg Cove behind you, and ahead a small pocket of sand pinned under the cliffs.
2
Swim inside a no-take marine reserve
The green shallows here have been closed to fishing since 1992, so the snapper below you are the fat, unbothered kind you rarely meet from a beach. Bring a mask: the rocks at the edges of the sand hold red moki, butterfish and crayfish tucked into the kelp.
3
Frame Te Hoho from the sand
The white stack standing off the beach is Te Hoho — pumice breccia, pinched almost through at the waist, with a tuft of pōhutukawa on its head. It is the shape that sells the Coromandel, and morning light off the sea is what gives it the pink-gold edge.
4
Come in from the sea by kayak or boat
Paddling in from Hahei you get the coast the walkers never see: the stacks, the blowholes and the sea caves cut into the same crumbling ash. It is also the honest backup plan — when rain shuts the clifftop track, the water is still open.
5
Detour to the Tokawhakairo lookout
A short side track off the clifftop route climbs to Tokawhakairo (McHands) Lookout, about 25 minutes return. From up there the pōhutukawa part and you see the whole bay and its islands at once — the drops are sheer, so keep back from the edge.
