Oneroa's beach is about a kilometre long, and the village sits only around 100 metres back from the sand. For the rest of the island, see our guides to sailing to Waiheke Island and Waiheke's Bottom End.

Getting there

From Westhaven, head out past North Head, run east along the south side of Rangitoto, then through the Motuihe Channel towards Matiatia. Round the headland north of Matiatia and follow the coast east into Oneroa Bay. It is about 14 nautical miles, so roughly 1¾ hours at 8 knots. Allow two to three hours in real conditions.

Keep a good lookout on the way. The Motuihe Channel has a fast passenger ferry lane, and ferries run in and out of Matiatia all day. Matiatia Bay itself is a prohibited anchorage under Auckland's navigation bylaw, so don't plan to stop there.

Anchoring in Oneroa Bay

Oneroa faces north. Cruising notes describe it as sheltered from any wind with south in it, with very good holding on firm sand. The flip side is that it's open to the north and north-east. If a northerly is forecast, swell rolls straight in and the bay becomes uncomfortable, so move somewhere more sheltered before it arrives.

Most boats anchor off the main beach, in front of the village. The bay shelves gently, so check chart NZ 5324 and your depth sounder, and allow for the tide falling overnight. On 'Zen', which draws 2.2 metres, anchor further out than the smaller yachts. Give swimmers plenty of room, and keep to 5 knots within 200 metres of the shore.

On summer holiday weekends, especially Christmas and New Year, the bay fills up. Arrive early and leave room to swing.

If the forecast swings north, the island's southern bays are the usual fallback. Our Waiheke guide covers Putiki and Huruhi bays.

Little Oneroa and the neighbouring bays

Little Oneroa

At the eastern end of the main beach, a rocky outcrop separates Oneroa from Little Oneroa. It's a smaller sandy beach and a little less built up. It suits the same southerly conditions as the main bay.

Enclosure Bay

A short way east, rocky Enclosure Bay is known for snorkelling at low tide. Treat it as a swim stop, not an overnight anchorage.

Owhanake Bay

West of Oneroa, between it and Matiatia, Owhanake is a quieter bay that also suits southerly weather. The coastal walk to Oneroa village passes along its shore.

Matiatia

Waiheke's main ferry terminal and a prohibited anchorage. Keep well clear of the ferries.

Going ashore

Take the dinghy to the beach, pull it well above the tideline and check the tide times. The village is a short walk up from the sand.

The village has cafés, restaurants, wine bars, galleries and gift shops, plus a small supermarket for bread, milk and ice. The island's bigger supermarket is at Ostend, and buses run from Oneroa.

Little Oneroa Reserve has a playground for all ages, toilets, picnic tables and an electric barbecue, so it's a good base for a family afternoon.

Walks

  • Oneroa to Palm Beach: About 6.4 km, 1½ to 2 hours, past Little Oneroa and Enclosure Bay. There are lots of steps and some steep sections.
  • Matiatia to Oneroa: About 5.5 km, roughly 2 hours, past Owhanake Bay and the historic Mokemoke Pā site. It isn't passable at Matiatia for 1½ hours either side of high tide.

Both walks are part of Te Ara Hura, Waiheke's 100 km walking trail.

Biosecurity, fishing rules and safety

  • Exotic caulerpa is close by. The formal "check and clean" controlled area runs from Palm Beach east around Thompsons Point to Onetangi Bay. You can anchor there, but must check and clean your anchor, chain and gear before moving. Local divers have also found caulerpa west of Oneroa Bay, in Owhanake Bay and outside the Enclosure Bay reef. Wherever you anchor, check your anchor and chain for seaweed, bag anything you find and bin it ashore. Check biosecurity.govt.nz/caulerpa before you go.
  • Keep the Gulf pest free. Check, clean and close: check the boat, dinghy and bags for rats, mice, ants and skinks, and keep food sealed. Report pests to 0800 DOC HOT (0800 362 468).
  • Leave the shellfish. Taking mussels, pāua and packhorse rock lobster is banned within one nautical mile of Waiheke until 6 August 2028, and scallops are closed under separate Gulf rules. Check the Fisheries New Zealand rules before taking anything.
  • Forecast and trip report. Check the MetService marine forecast for the Hauraki Gulf, and again before nightfall. Log a trip report with Coastguard on the app, by calling *500 or on VHF. In an emergency, call Maritime Radio on VHF channel 16.
  • Swimming. Check Safeswim for water quality, especially after heavy rain.

Suggested plans

A day trip

  • Morning: check the forecast for a southerly or light conditions, log your trip and sail for Oneroa.
  • Midday: anchor off the main beach, swim, then take the dinghy in for lunch in the village.
  • Afternoon: walk to Little Oneroa or snorkel Enclosure Bay. Check the anchor and chain for weed, then sail home in daylight.

An overnight or weekend

  • Saturday: sail out in the morning and anchor at Oneroa. Walk the coast to Palm Beach, then dinner ashore or on board.
  • Saturday evening: recheck the overnight forecast. If the wind is heading north, move to the south side of the island before dark.
  • Sunday: a swim or the Matiatia walk, then sail home.

YachtShare bookings run from one to 14 days, so a weekend at Oneroa fits easily. If a yacht is unbooked, members can ask management for a free freebie day after midday, and Oneroa is close enough for one.
