Puriri is one of the few native trees with large colourful flowers. Many plants in New Zealand have white or green flowers. The tubular flowers of the puriri look rather like snapdragon flowers and can range from fluorescent pink to dark red, rose pink (most common) or sometimes even to a white flower with a yellow or pink blush. The bright colour, the tube shape, copious nectar production and the hairs at the base of the flower tube all point towards birds pollinating this flower (the hairs stop insects from stealing the nectar).On the New Zealand mainland there is often plenty of nectar in the flowers because there aren't enough birds to eat all the nectar produced by the tree. http://www.terrain.net.nz/friends-of-te-henui-group/trees-native-botanical-names-r-to-z/puriri.html

North Island Weka (Gallirallus australis greyi) once widespread is now only found on the mainland in the hills between Matawai and Opotiki, where a few thousand survive. Since 2000, weka have been released near Russell, in the Whirinaki Forest and there is a small population on the margins of the Hauraki Gulf near Auckland. A substantial proportion of the population is on Kawau Island. Several other offshore island populations have also been established and they are also on Mokoia Island in Lake Rotorua. http://www.terrain.net.nz/Weka/

Metrosideros robusta, the northern rātā, is a forest tree endemic to New Zealand. It grows up to 25 metres (82 ft) or taller, and usually begins its life as a hemiepiphyte high in the branches of a mature forest tree; over centuries the young tree sends descending and girdling roots down and around the trunk of its host, eventually forming a massive, frequently hollow pseudotrunk composed of fused roots. In disturbed ground, or where there are gaps in the forest cover, Northern rātā will grow on the ground with a normal but short trunk. Rata on Wiki

The tui (Prosthemadera novaeseelandiae) is an endemic passerine bird of New Zealand, and the only species in the genus Prosthemadera. It is one of the largest species in the diverse Australasian honeyeater family, and one of two living species of that family found in New Zealand, the other being the related New Zealand bellbird. The species has a wide distribution in the archipelago, ranging from the subtropical Kermadec Islands to the sub-Antarctic Auckland Islands, as well as the main islands. Tui on Wiki

Ferns are mostly a tropical group, and New Zealand has an unusually high number of species for a temperate country. We have about 200 species, ranging from 10 m high tree ferns to filmy ferns just 20 mm long. About 40% of these species occur nowhere else in the world. Ferns are typically found in moist, forested areas because they require lots of water. Ferns are abundant in all damp situations in New Zealand forests, forming the undergrowth beneath a dense canopy of evergreen trees. They are also found growing on tree trunks and branches and along stream banks. Some hardy species have adapted to other drier habitats such as coastal, alpine, urban and even desert locations. Tree ferns are some of the most distinctive features of our forests. They occur in all forest types and are most plentiful in cut-over and degraded forests, where light levels are relatively high. They also appear in older plantations of exotic trees that are relatively open.

Korimako (bellbird) Anthornis melanura is a widespread species of passerine bird unique to New Zealand. It is the only living member of the genus Anthornis. It is found throughout the three main islands and many of the offshore islands including the Auckland Islands. Mammalian predators, such as rats and stoats, keep their numbers low. The females are dull olive brown, with a slight blue sheen on the head and a pale yellow cheek stripe. The males are an olive green, with a purplish head and black outer wing and tail feathers. The bellbird's song comprises three distinct sounds resembling the chiming of bells.
