The country’s unique geography and its impact on flora and fauna

New Zealand’s geography is truly one-of-a-kind, and it has played a significant role in shaping the country’s diverse flora and fauna.

As an island nation located in the southwestern Pacific Ocean, New Zealand has been isolated from the rest of the world for millions of years.

This isolation has allowed for the evolution of unique species that can’t be found anywhere else on Earth.

The country’s varied landscapes, including mountains, forests, coastline, and more, have also had a big impact on the development of its ecosystems.

Indeed, the different climate zones and ecosystems found throughout New Zealand provide habitats for a wide range of plant and animal life. From subtropical forests to alpine tundras, you’ll find a range of amazing taonga (treasures).

Exploring the lush forests of New Zealand

The New Zealand forest is a mesmerizing realm of natural wonders and breathtaking beauty. It may be home to some of the most dangerous animals in the country but the beauty and diversity of its animals far outweigh any risks.

Are you ready for an adventure?

Then pack your bags, because the forests of New Zealand are waiting!

These vibrant forests are home to an incredible variety of plant and animal life, and there’s so much to explore.

And if there’s one animal you’ll be on the look-out for, it’ll probably be the adorable kiwi bird!

This flightless bird is an emblem of New Zealand, and if you’re very lucky, you might find one in the country’s forests.

We’ll teach you all you need to know about meeting a kiwi shortly, but for now, back to the forest…

South Island forests and bush

One of the must-see forests in New Zealand is the temperate rainforest found on the West Coast of the South Island. This forest is a true natural wonder, with towering trees, dripping ferns, and a diverse array of plant and animal life (including the cheeky kea bird).

There, you’ll find the southernmost palm trees in the world (the nīkau palm) and a number of glaciers tucked in beside native bush.

North Island forests and bush

When visiting the North Island, make sure to keep an eye out for the iconic kauri tree, a species of tree that can grow up to 50 metres tall. They truly are a sight to behold.

In particular, we recommend you visit Tāne Mahuta, the largest kauri tree in New Zealand. Culturally significant to Māori, this giant tree is found in the Waipoua Forest within the Northland region.

Discovering the diverse birdlife of New Zealand

If you’re a bird enthusiast, then New Zealand is the place for you!

With a variety of landscapes and a rich history of isolation, the country is home to an incredible array of bird species, many of which are endemic and found nowhere else on Earth.

From the flightless kiwi to the cheeky kea, there are so many amazing birds to spot…

Pro tip: Though much of our bird life can be seen throughout New Zealand, some spots are known for more consistent sightings. We’ll share these below.

Kiwi are flightless, nocturnal birds with long beaks and an amazing sense of smell.

They’re only found in New Zealand and are so synonymous with the country that ‘kiwi’ is even the nickname given to locals. Unsurprisingly, they are also New Zealand’s most famous birds.

The North Island brown kiwi, the little spotted kiwi, and the great spotted kiwi are just a few of the different species you can find in different parts of the country. But be warned, these birds are very rare and as they’re nocturnal, they only come out at night.

See kiwi in the wild

Kiwi can be seen in different parts of the country. Some of the best places to see them in the wild include:

See kiwi in captivity

If you’d like to be sure of seeing a kiwi in New Zealand, it’s best to plan for a visit or two to a wildlife sanctuary or zoo.

Though these birds are nocturnal, dark rooms allow guests to see them during the day.

Another much-loved bird species in New Zealand is the kea. This is a species of parrot found in the South Island’s alpine regions.

These playful birds are known for their intelligence and mischievous behaviour. They have been known to interact with humans, especially those visiting the ski slopes. But beware – they’re also known for stealing food and shiny items, and even damaging cars!


If you’re into seabirds, then you won’t want to miss out on the many species that call New Zealand home.

From the albatross to the penguin, there’s a diverse array of species to discover.

In particular, you’ll want to keep an eye out for the little blue penguin. The world’s smallest penguin species, they can be found in many of the country’s coastal regions, including Dunedin (where lots of other wildlife can be spotted).

And let’s not forget the fantail (pīwakwaka in te reo Māori). Though these little guys aren’t as memorable as the rarer species, they are worth spotting.

This small bird has a distinctive fan-shaped tail. It’s found throughout the country; in fact, these friendly birds are often seen flitting about, interacting with humans and other birds too.

This small town is known for its incredible whale-watching opportunities, with sperm whales, humpback whales, and even the occasional orca making their home in the waters here.

The best season for whale watching in Kaikōura is between June and November. During this time, you can see a large number of whales and dolphins, though they are found in the region year-round.

Plus there’s a wealth of bird life to be found along the coastline, with penguins, albatrosses, and other sea birds making their homes there.

The plant life in New Zealand’s marine ecosystem is just as diverse and captivating.
