Tucetona laticostata, or the large dog cockle, is a salt water clam or marine bivalve mollusc in the family Glycymerididae. [1]
Despite the common name, it is not closely related to the common cockle. The word dog cockle implies that it roughly resembles a real cockle, but is not considered very good to eat, in other words, "only fit for dogs". Māori names include kuakua [2] and kuhakuha. [3]
The almost circular shell is thick and heavy with a dentate ventral margin, the valve exterior with strong flat radial ribs crossed with fine lines that fade toward the beak. Rare specimens exceed 120 millimetres in diameter, most are from 60 to 80 mm. Externally off-white to yellow or dirty pink, the brown periostracum is usually worn off the top half of the shell. Internally the valves are lustrous white, often with brown or purple markings. [4]
The large dog cockle is endemic to New Zealand, including Stewart Island and the Chatham Islands. Locally common, they can be found at and just below the surface of coarse sand or fine gravel substrate down to a depth of around 100 metres. T. laticostata is silt-tolerant and can form large densely populated beds, often with Purpurocardia purpurata , [4] though some can be found as solitary individuals.
The brown teal is a species of dabbling duck of the genus Anas native to New Zealand. For many years it had been considered to be conspecific with the flightless Auckland and Campbell teals in Anas aucklandica; the name "brown teal" has also been largely applied to that entire taxon. Common in the early years of European colonisation, the "brown duck" was heavily harvested as a food source. Its numbers quickly fell, especially in the South Island, and in 1921 they became fully protected. Captive breeding and releasing into predator-controlled areas has seen good localised populations re-introduced around the country in recent years.
Pāua is the Māori name given to three New Zealand species of large edible sea snails, marine gastropod molluscs which belong to the family Haliotidae, known in the United States and Australia as abalone, and in the United Kingdom as ormer shells. Pāua has entered English through common use in the New Zealand English dialect, and is both singular and plural, following the grammar rules of its original language.

Dosinia anus, commonly named the ringed dosinia, coarse dosinia, coarse biscuit shell and tuangi-haruru, in the Māori language, is a species of saltwater clam, a marine bivalve mollusc in the family Veneridae, the venus clams. The species is common to both of the main islands of New Zealand, where it is the largest and heaviest species in the genus, occasionally exceeding 80 mm in diameter. It buries itself in clean fine sandy substrata, sub-tidally down to 15 m deep.
Eudoxochiton nobilis, commonly called the noble chiton, is a large chiton of the family Callochitonidae. The Māori name is Rangitīra.
The common cockle is a species of edible saltwater clam, a marine bivalve mollusc in the family Cardiidae, the cockles. It is found in waters off Europe, from Iceland in the north, south into waters off western Africa as far south as Senegal. The ribbed oval shells can reach 6 centimetres (2.4 in) across and are white, yellowish or brown in colour. The common cockle is harvested commercially and eaten in much of its range.
Glycymerididae, often misspelled as Glycymeridae, common names dog cockles or bittersweets, is a worldwide family of salt water clams, marine bivalve mollusks in the order Arcida. They are related to the ark clams. This family contains 45 extant species in four genera.

The Wairau Bar, or Te Pokohiwi, is a 19-hectare (47-acre) gravel bar formed where the Wairau River meets the sea in Cloudy Bay, Marlborough, north-eastern South Island, New Zealand. It is an important archaeological site, settled by explorers from East Polynesia who arrived in New Zealand about 1280. It is one of the earliest known human settlements in New Zealand. At the time of the occupation it is believed to have been a low scrub-covered island 2 to 3 metres high, 1.1 kilometres (0.68 mi) long and 0.4 kilometres (0.25 mi) wide.

Austrovenus stutchburyi, common name the New Zealand cockle or New Zealand little neck clam, is an edible saltwater clam, a marine bivalve mollusc in the family Veneridae, the Venus clams. Its Māori name is tuangi or tuaki.
The Noises are a collection of islands lying northeast of Rakino Island in Auckland's Hauraki Gulf, off the coast of the North Island of New Zealand. The largest and most forested islands are Ōtata and Motuhoropapa; Orarapa and Maria/Ruapuke are also significant. After a rat eradication campaign in the 1960s, Maria was the first New Zealand island to become predator-free. The lack of invasive predators, intact native forest, and large numbers of breeding seabirds give the Noises significant conservation value. There has however been a marked decline in marine biodiversity surrounding the islands from over-fishing.
Glycymeris, common name the bittersweet clams, is a genus of saltwater clams, marine bivalve molluscs in the family Glycymerididae.
Moncks Cave is a cave located in Redcliffs, Christchurch. It is notable for the amount of wooden artefacts discovered there in 1889 by workmen while quarrying for road metal.
