Delaware Bay is a rural coastal locality in Nelson City, on the northern shore of Tasman Bay / Te Tai-o-Aorere, east of Pepin Island.
The public way in is Māori Pa Road, a side road off Cable Bay Road that ends beside the Delaware (Wakapuaka) Estuary. This is not a suburban strip of shops and schools. It is a small rural-residential stretch of coast, known for its estuary, its fishery and the shipwreck rescue that gave the bay its English name.
The estuary is of deep cultural significance to local iwi, and driving vehicles across the foreshore is not permitted. People come for the quiet road end, the birdlife and the short walk at Paremata Reserve.

About Delaware Bay
Vehicle access across the Delaware (Wakapuaka) Estuary is restricted. Under the Nelson Resource Management Plan, driving on the estuary to launch or retrieve boats, and disturbing the foreshore with vehicles, is not permitted.
Nelson City Council enforcement officers monitor launching activity and direct people to the authorised ramps at Cable Bay, Monaco and the Nelson Marina. The marina slipway is the safest all-weather launch site in the city.
The bay is an indentation in the coast east of Pepin Island, inside the larger Tasman Bay / Te Tai-o-Aorere. A narrow sandbar separates it from Cable Bay and links Pepin Island to the mainland.
The sheltered water inside that spit is the estuary of the Wakapuaka River, also called Delaware Inlet. From the end of the public road you look across mudflats and a shallow channel, with Bishop’s Peninsula reaching into the estuary and Pepin Island beyond.
The English name comes from the brig Delaware, which ran onto rocks at Wakapuaka in September 1863 on its maiden voyage from Nelson to Napier. Local Māori reached the wreck through rough water.
Hūria Mātenga, with her husband Hemi Mātenga and others, helped get a line ashore and bring the crew off. The wider Wakapuaka area has a much longer history as a place of settlement, food gathering and burial. Bishop’s Peninsula is a Māori reserve.
Local iwi, including Ngāti Tama, hold the estuary and the land around it as places of longstanding significance, including wāhi tapu and urupā. From pre-European times the estuary has been a place for gathering kai moana, tied to manaakitanga and kaitiakitanga.
The coast from Delaware Bay to Glenduan became a taiapure, a traditional fishery reserve under the Fisheries Act 1993, in 2002. A committee of iwi, community and marine group representatives manages it.
Today the locality is a scatter of rural-residential properties along Māori Pa Road, beyond the council water network. Some of those properties are on a private community scheme that draws raw water from Māori Pa Stream, with treatment left to each household. There is no shop, school or town centre.
The character is coastal and quiet, with working land, estuary flats and a public road end that has long attracted people launching small boats, even as the rules now keep vehicles off the foreshore.
Access and the Estuary
Māori Pa Road was opened to public vehicles in 1999, and an informal launch track at the eastern side of the estuary became popular because it is more sheltered than the open coast at Cable Bay. That use damaged seagrass and cockle beds and conflicted with cultural values.
Council, iwi, residents and boat users have argued over access for years, including in the Environment Court. The planning rule is clear: vehicles do not belong on the estuary. Launch and retrieve only at a designated ramp.
If you are visiting on foot, park considerately near the end of the public road and stay off private land. Bishop’s Peninsula is not a public reserve.
The estuary edge can be soft mud, and the channel changes with the tide. This is not a patrolled swimming beach, and there are no public toilets or other visitor facilities at the road end.
History and Heritage
The 1863 wreck is the episode most visitors hear about, but it sits inside a longer Māori history of Wakapuaka. The rescue made Hūria Mātenga widely known. She and her companions swam out in heavy seas, secured a line and helped haul the crew to shore.
The story is why a bay in Te Tauihu carries the name of an American state, via a Nelson-built brig, rather than a name from the land itself.
Title to the estuary has also been contested in the courts. In 1998 the Māori Land Court recognised Te Hūria Mātenga Wakapuaka Trust as holding freehold title. The Crown challenged that finding, and in 2011 the Supreme Court dismissed the trust’s bid for freehold title.
Customary association with the estuary did not end with that case. Ngāti Tama, Wakapuaka 1B Incorporation and Te Hūria Mātenga Wakapuaka Trust have all been part of the more recent argument over vehicles on the flats.
Getting Outdoors
The outdoors here is estuary, spit and a short walk, not a park network. Paremata Reserve, just across the bridge on Māori Pa Road, is the start of a council walk of about 40 minutes.
The track passes electric fences and stiles, with side access to the river, and opens onto views of Pepin Island, Cable Bay, Bishop’s Peninsula and Delaware Bay. Herons and spoonbills use the mudflats.
The sandspit is important breeding habitat for pohowera (banded dotterel) along the Nelson City coast, and the bay also holds a small winter flock. Seagrass and cockle beds in the estuary are spawning grounds for fish.
Give nesting birds space, especially on the spit, and do not drive onto the flats to reach a fishing spot. Gathering kai moana sits inside the taiapure, so check the current fishery rules before you take anything.

Frequently Asked Questions
Is Delaware Bay part of Nelson?
Yes. It is a rural locality inside Nelson City, north of the urban area, reached by Cable Bay Road and Māori Pa Road.
How do I get to Delaware Bay?
Follow State Highway 6 north from Nelson, turn onto Cable Bay Road, then right into Māori Pa Road. The public road ends near the estuary. Cable Bay Road and Māori Pa Road are posted at 80 km/h because they are narrower and less protected than the state highway.
Can I drive onto the estuary to launch a boat?
No. The Nelson Resource Management Plan does not permit driving vehicles on the estuary to launch or retrieve boats, or disturbing the foreshore with vehicles. Use an authorised ramp at Cable Bay, Monaco or the Nelson Marina. The marina slipway is the safest all-weather option.
Why is it called Delaware Bay?
It is named after the brig Delaware, wrecked on rocks at Wakapuaka in September 1863 on its maiden voyage from Nelson to Napier. Local Māori, including Hūria Mātenga, rescued the crew.
Is there a shop or a school in Delaware Bay?
No. There is no shopping centre and no school in the locality. It is a small rural-residential area, and everyday services are in Nelson.
What is the taiapure?
The coast from Delaware Bay to Glenduan is a taiapure, a traditional fishery reserve set up in 2002 under the Fisheries Act 1993. A committee of iwi, community and marine group representatives manages it.
Can I walk at Delaware Bay?
Yes. Paremata Reserve, just across the bridge on Māori Pa Road, is the start of a short council walk with views toward Pepin Island, Cable Bay and Bishop’s Peninsula. Stay on the public track, mind electric fences, and do not treat Bishop’s Peninsula as public land. It is a Māori reserve.
Is the water on tap from the council?
No. The locality is beyond the council reticulated network. Some properties on Māori Pa Road are supplied by a private scheme drawing raw water from Māori Pa Stream, and each household is responsible for making that water safe to drink.
