Onemana Beach is a small surf beach on the eastern Coromandel Peninsula, between Whangamatā and Pāuanui, about 65 kilometres north of Tauranga in a straight line. The village is about three kilometres off State Highway 25, which makes it a quiet alternative to the busier Coromandel beaches for a day trip from Tauranga.
LAWA describes it simply as a patrolled beach, and volunteer lifeguards from Onemana Surf Life Saving Club watch over the flagged area in summer. Waikato Regional Council tests the water beside the surf club every week over summer, and the site holds an Excellent long-term grade on LAWA. Toilets, showers, a playground and parking are all close to the beach.

About Onemana Beach
Onemana is a village on the eastern side of the Coromandel Peninsula, in the Thames-Coromandel District of the Waikato region. It lies about three kilometres east of State Highway 25, south of Pāuanui and north of Whangamatā, with the Wharekawa River and Opoutere just to the north and west.
The land around the bay has a long human history. Archaeological work published by Auckland Museum found evidence of settlement going back centuries, with a pā site south of the beach and stone tool making in the area.
Much of that archaeological site was lost when the modern village was laid out as a subdivision on farmland in the 1970s, and the name Onemana dates from that subdivision.
The beach itself is a mix of sand and rocky reef, with a stream flowing out into the middle of the bay. Waikato Regional Council lists Onemana as a surf break of regional significance, describing a punchy, hollow and fast beach break that works best on a north-east swell, an offshore westerly wind and mid tide.
Onemana Surf Life Saving Club, formerly Onemana Beach Rescue, was set up in 1989 and ran its first beach patrols in the summer of 1990/91, with three lifeguards on the beach every day over the main Christmas holiday period.
The club describes itself as one of the smallest in New Zealand, with an active Nippers group, and it was named Coromandel Patrol Club of the Year at the 2023 Bay of Plenty and Coromandel Awards of Excellence. Public toilets and a shelter near the beach were built in 2019 with help from the Tourism Infrastructure Fund.
Swimming and Water Quality at Onemana Beach
LAWA describes Onemana as a patrolled beach and asks swimmers to stay between the flags. Patrol hours change from season to season, so check the latest times on Safeswim before you go.
Outside patrol hours there are no lifeguards, and LAWA warns swimmers to watch for rips, strong currents, sudden drop-offs and underwater objects. With rocky reef along parts of the beach, swim between the flags and if in doubt, stay out.
Waikato Regional Council samples the sea beside the surf club every week from November to March and sends the results to LAWA. The site has an Excellent LAWA long-term grade, based on 110 routine tests over the summers of 2020/21 to 2024/25. Across 129 tests between November 2019 and March 2025, 98% were suitable for swimming.
An Excellent grade means the water has rarely been found unsuitable for swimming, but it is a long-term record, not a promise for any given day: LAWA can still post a temporary “unsuitable for swimming” notice after a poor result, as it did for Onemana in late February 2026.
Check the latest status on LAWA before you swim, and stay out of the water for at least 48 hours after heavy rain.
LAWA advises avoiding swimming for two to three days after heavy or prolonged rain, even at sites with generally good water quality, and waiting until floodwater discolouration has cleared, since floodwater can carry high levels of E. coli and other bacteria.
Getting There from Tauranga
Onemana is a straightforward day trip from Tauranga. Head north on State Highway 2 to Waihī, then follow State Highway 25 north through Whangamatā and turn off towards the coast for the last three kilometres to the village.
Parking, toilets, showers and a playground are all within a short walk of the surf club. Whangamatā, on the way, is the nearest town for shops and cafés.
Dog owners should check the Thames-Coromandel District Council dog rules before leaving home. The council says dogs are generally allowed off lead on its beaches, but many beaches have restrictions over summer, often from Labour Weekend to 1 March during the dotterel nesting season.
Signs at the beach entrance show the local rule: green for off-lead exercise, orange for on-lead at the times shown, and red for no dogs.
