The Dun Mountain-Maitai Terrane comprises the Dun Mountain Ophiolite Belt, Maitai Group and Patuki Mélange. The Dun Mountain Ophiolite is an ophiolite of Permian age located in New Zealand's South Island. Prehistorically this ophiolite was quarried by Māori for both metasomatized argillite and pounamu (jade) which was used in the production of tools and jewellery.

The Tasman Region, and the small adjoining Nelson Region, form one of the more geologically interesting regions of New Zealand. It contains the oldest rocks of anywhere on New Zealand's main islands. It contains all the main terranes that make up New Zealand's basement. These basement rocks include Ultramafic rocks, such as Serpentine and Dunite, and valuable minerals, such as Gold. The Nelson Region is bordered to the south by the Alpine Fault, the main fault forming the boundary between the Pacific Plate and the Indo-Australian Plate, that generated the Southern Alps.

The Haast Schist which contains both the Alpine and Otago Schist is a metamorphic unit in the South Island of New Zealand. It extends from Central Otago, along the eastern side of the Alpine Fault to Cook Strait. There are also isolated outcrops of the Haast Schist within the central North Island. The schists were named after Haast Pass on the West Coast. The Haast Schist can be divided geographically from north to south into the Kaimanawa, Terawhiti, Marlborough, Alpine, Otago and Chatham schist.

The Marlborough Sounds Important Bird Areas are four distinct sites comprising several small, rocky islets contained within an area with a maximum linear extent of 40 km, in New Zealand. They lie close to Cook Strait in the outer Marlborough Sounds at the northern end of the South Island. The sites are Duffers Reef, Sentinel Rock, White Rocks and the Trio Islands. They have been identified as Important Bird Areas (IBAs) by BirdLife International because they hold the only known colonies, and encompass the entire breeding range, of the vulnerable rough-faced shag.

Molesworth Station is located behind the Inland Kaikoura Mountain range in the South Island's Marlborough District. It is New Zealand's largest farm, at over 1,800 km², and supports the country's biggest herd of cattle. It also hosts government science programs, such as research into bovine tuberculosis and related research into possums. The station helps rabbit population reduction.

Picton Aerodrome is a Non-Certificated Aerodrome 4 NM south of Picton township in the Marlborough District of the South Island in New Zealand. Sounds Air has 5 flights per day to Wellington. The Marlborough Sounds Airpark is located nearby offering 16 private hangars adjacent to the main runway with remote control access for the owners to park their aircraft. On 2 January 1986 seven people died when a Cessna aircraft crashed on takeoff near Picton. Later in another accident on 29 January 1996 five died when a Cessna Caravan crashed on approach to Picton.

Te Whanganui / Port Underwood is a sheltered harbour which forms the north-east extension of Cloudy Bay at the northeast of New Zealand's South Island, on the east coast of the Marlborough Sounds. With only a relatively narrow entrance to the south-south-east it is sheltered from almost all winds. Originally considered part of Cloudy Bay the port was named after Joseph Underwood of the shipping firm Kabel and Underwood in the early 19th century.

The Torlesse Composite Terrane is a plate tectonic terrane forming part of the South Island of New Zealand. It contains the Rakaia, Aspiring and Pahau Terranes and the Esk Head Belt. Greywacke is the dominant rock type of the composite terrane; argillite is less common and there are minor basalt occurrences. The Torlesse Composite Terrane is found east of the Alpine Fault in the Southern Alps of New Zealand. Its southern extent is a cryptic boundary with the Caples Terrane within the Haast Schists in Central Otago. It is named for the Torlesse Range in Canterbury.

Waihopai Valley is an area near Blenheim in the Marlborough region of the South Island of New Zealand. The Waihopai River drains the area.
