New Zealand's Awesome Landscape
You'll find a variety of awesome landscapes
in New Zealand, all within easy reach
of each other. Spectacular glaciers, picturesque
fiords, rugged mountains, vast plains,
rolling hillsides, subtropical forest,
volcanic plateau, miles of coastline with
gorgeous sandy beaches - its all
here. No wonder New Zealand is becoming
so popular as a location for movies!
What's
There?
Lying in the south-west Pacific, New
Zealand consists of two main islands
- the North Island and the South Island.
In addition, Stewart Island and many
smaller islands lie offshore. The North
Island has a 'spine' of mountain ranges
running through the middle, with gentle
rolling farmland on both sides. The
central North Island is dominated by
the Volcanic Plateau, an active volcanic
and thermal area. The massive Southern
Alps form the backbone of the South
Island. To the east of the Southern
Alps is the rolling farmland of Otago
and Southland, and the vast, flat Canterbury
Plains. [ more about 'The Plains']
Leaving
Home - How it Began
New Zealand's oldest rocks are over
500 million years old, and were once
part of Gondwanaland. This massive supercontinent
started to split up about 160 million
years ago, and New Zealand separated
from it about 85 million years ago.
New
Zealand sits on two tectonic plates
- the Pacific and the Australian. Fifteen
of these gigantic moving chunks of crust
make up the Earth's surface. The North
Island and some parts of the South Island
sit on the Australian Plate, while the
rest of the South Island sits on the
Pacific. Because these plates are constantly
shifting and grinding into each other,
New Zealand gets a lot of geological
action.
The
186 AD Taupo eruption threw ash 50 km
into the air, and caused a layer of
ash five metres deep to be deposited
throughout the volcanic plateau.
Being straddled over two tectonic plates
and sitting on the Pacific ring
of fire can have its disadvantages
in the form of volcanoes, earthquakes
and other natural hazards. However,
this subterranean activity also blesses
New Zealand with some spectacular geothermal
areas and relaxing hot springs, as well
as providing electricity and heating
in some areas.
Rotorua
is the centre of geothermal tourist
activity, with plenty of mud pools,
geysers, and hot springs in its active
thermal areas not to mention
its trademark Sulphur City
smell. First settled by Maori who used
the hot springs for cooking and bathing,
Rotorua soon attracted European residents.
The reputed health benefits of its hot
pools quickly earned the area the name
of Cureland.
In
addition to Rotorua, you can enjoy hot
springs and other thermal activity in
most regions of the North Island north
of Turangi, as well as in Hanmer Springs
and the West Coast in the South Island.

From
Long Sandy Beaches to Wild, Rugged Coastlines
New Zealand has over 15,000 kilometres
of beautiful and varied coastline. In
the Far North and on most of the East
Coast of the North Island youll
find long sandy beaches perfect for
swimming, surfing and sunbathing. The
North Islands West Coast has dark
sandy beaches, with sand heavy in iron.
The north of the South Island has some
beautiful sandy beaches, while the coastline
around the rest of the South Island
tends to be wilder and more rugged.
Mountain
Range to Fertile Farmland
About a fifth of the North Island and
two-thirds of the South Island are mountains.
The existence of a spine
of mountain ranges throughout New Zealand
is also due to the movement of the earths
tectonic plates. Stretching from the
north of the North Island to the bottom
of the South, these mountains are caused
by the collision of the Australian and
Pacific Plates.
Over
millions of years, alluvial deposits
(eroded from the mountains by rivers)
formed the vast Canterbury Plains in
the South Island and a number of smaller
plains in the North. These alluvial
plains contain some of New Zealands
most fertile and productive farmland
Glaciers
of Grinding Ice
New Zealands Southern Alps have
a number of glaciers, the largest being
Tasman glacier, which you can view by
taking a short walk from Mount Cook
village. New Zealands most famous
glaciers are the Franz Josef and Fox
on the South Islands West Coast.
Gouged out by moving ice over thousands
of years, these spectacular glaciers
are easily accessible to mountaineers
and hikers. You can walk up to the glaciers
or do a heli-hike fly up by helicopter
and walk down.
Sunken
Mountains
Over thousands of years, the process
of subduction has seen parts of the
New Zealand landscape become submerged.
The Marlborough Sounds and Fiordland
are examples of high mountain ranges
that have sunk into the
sea, creating spectacular sounds and
fiords. These areas provide some of
New Zealand most picturesque scenery,
with steep lush hills plunging down
to the deep still bays below. Clear,
deep still water surrounded by beautiful
bush makes these areas ideal for boating
and kayaking.
