The Hen and Chicken Islands (usually known collectively as the Hen and Chickens) lie to the east of the North Auckland Peninsula off the coast of northern New Zealand. They lie 12 kilometres (7.5 mi) east of Bream Head and 40 kilometres (25 mi) south-east of Whangarei.

History[edit]

These islands were named by Captain James Cook, who first sighted them in 1769. It has been suggested that the name was inspired by an old name for the star cluster usually known as the Pleiades (and called Matariki by the Māori).

Originally owned by the Māori Ngā Puhi iwi, they were sold to the New Zealand Government in 1883. The islands were made a scenic reserve in 1908 owing to the rarity of their flora and fauna, and became a wildlife refuge in 1953. Hen Island had actually passed from Māori hands a few years earlier, being bought by Thomas Outhwaite in 1872. It was bequeathed to the nation by his daughter Isa Outhwaite in 1927, and it too was named as a scenic reserve.

In June 1940, the Mail Liner RMS Niagara sank off the islands after hitting a mine. Most of the cargo, which included gold bullion, was later salvaged.

Environment[edit]

The islands are noted for their bird life, with colonies of seabirds as well as forest birds which have become scarce or extinct on the mainland. The islands have been identified as an Important Bird Area, by BirdLife International because they are home to a breeding population of about 500 pairs of Pycroft's Petrels.[1]

The islands[edit]

Hen Island, or Taranga lies separate from the rest of the chain, lying 7 kilometres (4.3 mi) to the southwest. It is also considerably larger than the Chicken Islands, or Marotiri, which comprise a chain of five small islands running north-west to south-east to the north of Hen Island. The chain consists of Wareware and Muriwhenua Islands (together forming North West Chicken), Mauitaha (West Chicken), Lady Alice Island (Big Chicken or Motu Muka), Whatupuke (Middle Chicken), and Coppermine Island (Eastern Chicken).

Taranga (Hen) Island[edit]

Taranga is the largest island by some considerable margin, totalling 4.7 km2 (2 sq mi). Long and thin, it has a length of 6 kilometres (3.7 mi) and an average width of less than 1,000 metres (1,094 yd). A remnant of a four-million-year-old volcano, the island is dominated by a rocky ridge reaching to about 417 metres (1,368 ft) at its highest point, called "The Pinnacles". Sail rock, a stack, rises from the ocean 3 kilometres (1.9 mi) to the south of Hen Island and is a prominent navigational point for yachts.

By the late 1800s Hen Island was the only place in New Zealand with a surviving population of North Island Saddleback. The once common species of forest bird found in the North Island, was decimated by the human introduction of mammalian predators, such as rats and stoats. In the 1960s translocations of saddleback from Hen Island to other island sanctuaries around New Zealand began.[2]

Muriwhenua and Wareware[edit]

Two small rocky islands with a combined area of 3 ha (7.4 acres).

Lady Alice Island[edit]

Named after Lady Alice Fergusson (wife of Governor General Sir Charles Fergusson), it is the largest of the five Chickens and is of particular significance because of its flora and fauna. The island covers 1.4 km2 (0.54 sq mi) and is surrounded by rocky reefs. It was occupied by Māori until the 1820s, and was used as a base for fishermen in the 1890s. Cattle were introduced at about this time, but were removed in the 1920s.

Whatupuke[edit]

Formerly known as Whakahau this island is composed of a large eastern section and a peninsula to the southwest. The coast of the peninsula forms one of the chain's main land features, a 300-metre (328 yd) wide bay (Starfish Bay). The island covers 1 km2 (0.39 sq mi), and is steep, rising to 234 metres (768 ft).

Coppermine Island[edit]

Coppermine island covers an area of 75 ha (190 acres). It is composed of two sections joined by a short isthmus. As the name suggests, there are copper deposits on the island, but attempts at mining them in 1849 and 1898 proved unprofitable.

Mauitaha[edit]

This 20 ha (49 acres), rugged, scrub-covered rock lies 1 kilometre (0.62 mi) to the south of Muriwhenua. It rises to 125 metres (410 ft).

The New Zealand Department of Conservation and the Ngati Wai iwi have entered into partnership to set up a sanctuary for the Polynesian Rat, or Kiore, on the islands Mauitaha and Araara. A spokesman for Ngati Wai said the kiore heritage will be protected as the movement of the kiore through the Pacific paralleled the migration of the New Zealand Maori. A spokesman for the Department of Conservation said the Department's policy change from eradication would assist scientific research.
