D'Urville Island, Māori name Rangitoto ki te Tonga, is the largest island in the Marlborough Sounds, on the northern coast of the South Island of New Zealand. It was named after the French explorer Jules Dumont d'Urville.

The local authority is the Marlborough District Council.
The Waikato River is the longest river in New Zealand, running for 425 kilometres (264 mi) through the North Island. It rises on the eastern slopes of Mount Ruapehu, joining the Tongariro River system and flowing through Lake Taupō, New Zealand's largest lake. It then drains Taupō at the lake's northeastern edge, creates the Huka Falls, and flows northwest through the Waikato Plains. It empties into the Tasman Sea south of Auckland, at Port Waikato. It gives its name to the Waikato region that surrounds the Waikato Plains. The present course of the river was largely formed about 17,000 years ago. Contributing factors were climate warming, forest being reestablished in the river headwaters and the deepening, rather than widening, of the existing river channel. The channel was gradually eroded as far up river as Piarere, leaving the old Hinuera channel through the Hinuera Gap high and dry. The remains of the old course are seen clearly at Hinuera, where the cliffs mark the ancient river edges. The Waikato's main tributary is the Waipā River, which converges with it at Ngāruawāhia.
The Clutha River is the second longest river in New Zealand and the longest in the South Island. It flows south-southeast 338 kilometres (210 mi) through Central and South Otago from Lake Wānaka in the Southern Alps to the Pacific Ocean, 75 kilometres (47 mi) south west of Dunedin. It is the highest volume river in New Zealand, and the swiftest, with a catchment of 21,000 square kilometres (8,100 sq mi), discharging a mean flow of 614 cubic metres per second (21,700 cu ft/s). The river is known for its scenery, gold-rush history, and swift turquoise waters. A river conservation group, the Clutha Mata-Au River Parkway Group, is working to establish a regional river parkway, with a trail, along the entire river corridor.
The Buller River is a river in the South Island of New Zealand. The Buller has the highest flow of any river in the country during floods, though it is only the 13th longest river; it runs for 177 km (110 mi) from Lake Rotoiti through the Buller Gorge and into the Tasman Sea near the town of Westport. A saddle at 710 m (2,330 ft) separates the Buller from the Motupiko River and that is divided from the Wairau River by a 695 m (2,280 ft) saddle, both aligned along the Alpine Fault, as is the top of the Buller valley.
The Kawarau River is a river in the South Island of New Zealand. It drains Lake Wakatipu in northwestern Otago via the lake's Frankton Arm. The river flows generally eastwards for about 60 kilometres (37 mi) and passes through the steep Kawarau Gorge until it joins Lake Dunstan near Cromwell. Before the construction of the Clyde High Dam, the Kawarau joined the Clutha River / Mata-Au in a spectacular confluence at Cromwell. The Shotover River enters the Kawarau from the north; the Nevis River enters it from the south. With many rapids and strong currents, the river can be dangerous and has claimed many lives. It is popular for bungy jumping and kayaking.
The Taieri River is the fourth-longest river in New Zealand and is in Otago in the South Island. Rising in the Lammerlaw Range, it initially flows north, then east around the Rock and Pillar range before turning southeast, reaching the sea 30 kilometres (19 mi) south of Dunedin.
The Nevis River is in Otago, New Zealand. It flows north for 40 kilometres (25 mi) through rough country before meeting the Kawarau River, of which it is a tributary. A prominent rock outcrop close to this junction is known as the Nevis Bluff.
The Taramakau River is a river of the West Coast Region of the South Island of New Zealand. It rises in the Southern Alps / Kā Tiritiri o te Moana near Harper Pass, 80 kilometres (50 mi) due east of Hokitika, and runs westward for 75 kilometres (47 mi) into the Tasman Sea 15 kilometres (9.3 mi) south of Greymouth.

The Mōkihinui River is a river located on the West Coast of New Zealand's South Island, about 40 kilometres north of Westport. Meridian Energy had proposed the Mokihinui Hydro project on the river in 2007 but it was cancelled in May 2012. In 2019, it was announced that 64,400 ha of land in the Mōkihinui River catchment, including 15 km (9.3 mi) of river bed, would be added to Kahurangi National Park.
Fox Glacier, called Weheka until the 1940s, is a village on the West Coast of the South Island of New Zealand. The village is close to the eponymous Fox Glacier / Te Moeka o Tuawe.
The Mokihinui Hydro was a proposed hydroelectric dam and power station planned for conservation land on the Mōkihinui River on the West Coast of New Zealand. The project by Meridian Energy was expected to cost $300 million.
The Pororari River, with an older spelling of Porarari, is a river of the West Coast Region of New Zealand's South Island. It flows northwest from its sources in the Paparoa Range, reaching the Tasman Sea at Punakaiki via Pororari Lagoon. Cave Creek / Kotihotiho is a tributary to the river. There are opportunities to tramp along this river, with two different options accommodating multi-hour loop walks. Further upstream, the Pororari River is followed by the new Paparoa Track, which provides an opportunity for multi-day tramping or mountain biking.
The Puhi Puhi River is a river of the Marlborough Region of New Zealand's South Island. It flows southwest, roughly paralleling the Pacific Ocean coast, from its source 12 kilometres (7 mi) west of the mouth of the Waiau Toa / Clarence River, and reaches its outflow into the Hāpuku River 5 kilometres (3 mi) from the latter's mouth at Hapuku. One of the tributaries is the Clinton River.
The Waikaia River is a river in New Zealand, a tributary of the Mataura River. The name is probably a corruption of Wai-o-Whakaea.
