The arrival of people to New Zealand significantly changed the face of our landscape.

In the space of about 750 years, native forest cover has been reduced from 85% of the land area (23 million hectares) to about 23% (6.2 million hectares).

Most of New Zealand’s lowland forests, wetlands, dunes, and estuaries have been converted into pasture or towns, with original ecosystems reduced to a patchwork of isolated fragments.

Pasturelands & exotic forests

Before people arrived to New Zealand, about 5% of our land area was grassland. Today, grass covers more than 38% of New Zealand’s total land area, 52% of the North Island and 29% of the South Island. Pastureland is not good kiwi habitat.

Exotic forests are a mixed blessing for kiwi. Birds can be at risk when land is cleared for planting, but kiwi do live in established plantation forests.

In 2006, planted forest was estimated to cover 1.8 million hectares of New Zealand’s total land area. However, since the dairying boom began, fewer exotic forests are being replanted and some immature forest is being converted to dairy pasture. This could turn out to be bad for kiwi.

The impact of clearing land

Land clearance affects kiwi in three main ways:

  • Kiwi can be killed when land is cleared by burning, and by the large rollers used to crush vegetation.
  • It concentrates kiwi and their predators into smaller areas.
  • The kiwi’s social organisation is affected. Kiwi are ferociously territorial. Less habitat means more competition for space, more boundary wars, less breeding, and more birds pushed out into farmland where they can be attacked by dogs.

Kiwi aren’t fussy

Thankfully kiwi are adaptable and live in a huge range of habitats, from native forest and scrub, to rough farmland and plantation forests, right through to sand dunes, snowy tussocks, and even mangroves. They especially like places where stands of trees run down to rivers and include pockets of wetland vegetation.

Because they are soil feeders, kiwi prefer places where they can get straight to the dirt, rather than having to probe through the thick leaf litter of a forest floor. They dislike places that are trampled by livestock because the ground is so compacted.

Kiwi can survive quite well when predators are controlled, enough shelter and feeding places are available, and the ground is not too dry or compacted.

Kiwi species

All kiwi are the same, right? Wrong. There are actually five different species of kiwi, all with their own unique features.

Threats to kiwi

The national kiwi population is under attack from many different threats, including predators, loss of habitat, and fragmentation of species.

Where to see kiwi

Many facilities around New Zealand are home to kiwi, plus there are places where, if you're lucky, you could see one in the wild too.
