About Onemana
Onemana is a small, upmarket beach settlement tucked into a sheltered bay about 5 kilometres north of Whangamata on the Coromandel Peninsula. With no shops, no cafes and fewer than 100 permanent residents, it is the polar opposite of its busier neighbour. What it does have is a beautiful crescent beach, pohutukawa-shaded picnic spots, excellent rock pools and a genuine sense of peace and quiet. If Whangamata is the party, Onemana is the morning after — calm, beautiful and unhurried.
The settlement is accessed via a sealed road off SH25A, about 5–10 minutes’ drive north of Whangamata. Most properties here are holiday homes and baches, ranging from modest 1970s originals to modern architecturally designed houses. There are no commercial services in Onemana — for groceries, fuel and dining you need to drive to Whangamata.
Onemana Beach Locations & Features
Onemana Beach
Onemana Beach is a 600-metre crescent of golden sand set between two rocky headlands. The bay faces north-east, which means it is more sheltered from the prevailing south-west winds than Whangamata Beach. Waves here are typically smaller and gentler — often half the size of what is breaking at Whangamata on the same day. This makes it a popular choice for families with younger children and for swimmers who prefer calmer conditions. The pohutukawa trees along the back of the beach provide natural shade, something that is rare on most Coromandel beaches.
Onemana Rock Pools
At both ends of Onemana Beach, volcanic rock platforms extend out from the headlands. At low tide — especially low spring tides — these platforms are exposed and create a maze of shallow rock pools teeming with marine life. You will find crabs, small fish, anemones, hermit crabs, limpets and, if you look carefully, the occasional octopus. The southern rock pools (towards Whangamata) tend to be larger and more varied. This is a fantastic activity for children, and far more accessible than most Coromandel rock pool spots because the platforms are relatively flat and easy to walk on.
Onemana Headland Walk
A short but rewarding walking track climbs up from the southern end of Onemana Beach onto the headland separating Onemana from Whangamata. The track passes through coastal bush — pohutukawa, karaka and nikau palm — before reaching a lookout point with panoramic views over Onemana Bay to the north and down the coast towards Whangamata to the south. On clear days you can see Mayor Island (Tuhua) on the horizon. The track is well-formed but includes some steep sections and steps. Allow 30–45 minutes for the return trip.
Getting to Onemana
From Whangamata, head north on SH25 towards Thames. After about 3 kilometres, turn right onto Onemana Drive (signposted). The road winds through bush and farmland for about 2 kilometres before reaching the settlement. The drive takes 5–10 minutes. From the north (Thames/Tairua direction), the Onemana turnoff is on the left shortly before you reach Whangamata.
Practical Tips for Visiting Onemana Beach
- Parking is very limited: The small beach car park fills early in summer. Arrive before 10am during peak season or be prepared to park on the road and walk
- Bring everything: There are no shops in Onemana. Bring all food, water, sunscreen and supplies from Whangamata
- No lifeguards: The beach is never patrolled. Swim with caution and supervise children closely
- Respect the residents: Onemana is a quiet residential area. Keep noise down, do not block driveways, and take all rubbish with you
- Mobile coverage: Coverage can be patchy in Onemana. Do not rely on your phone for tide times — check before you leave Whangamata
- Sunset: Because the bay faces east, Onemana does not get ocean sunsets — but the sunrise over the Pacific is spectacular. Worth an early start if you are staying nearby
Accommodation
There are no motels, hotels or campgrounds in Onemana. Accommodation is exclusively private holiday homes, available through Bookabach, Airbnb and local Whangamata rental agencies. Properties range from modest baches to high-end homes and tend to book out well in advance for the Christmas–New Year period. For budget options, stay in Whangamata and drive to Onemana for the day — it is only 5 minutes away.
