About 230 km from Auckland and 80 km from Taupo, Rotorua sits at the edge of a
lake that fills a huge volcanic caldera and the city is riddled with hot
springs, craters, geysers and pools of bubbling mud. It's at an elevation of
about 300m on the north-eastern edge of the central volcanic plateau. This area
was built up by hundreds of thousands of years of eruptions from the Taupo
Volcanic Zone that underlies the land from Mount Ruapehu and Taupo,
through Rotorua and out to steaming White Island off the coast.
Maori History
The local Maori are the Te Arawa tribes. According to tradition, they came from
the ancestral homeland of Hawaiiki in the Te Arawa waka (canoe) and settled at
first on the coast. Their tohunga (high priest), Ngatoro-i-rangi, created the
region's lakes by stamping his foot in the dry earth as he travelled inland to
Lake Taupo and the mountains of Tongariro and Ruapehu. On the cold summit of
Tongariro he was caught in a blizzard and called to his sisters in Hawaiiki to
send him fire for warmth. It came under the sea and land, bursting out at
White Island, Rotorua and Taupo before bringing the mountains to roaring
eruption. It is this fire that still warms the land today.

Ihenga, the grandson of the canoe's captain, explored the region and named the
lakes. Travelling inland, he found Lake Rotoiti first, and called it Te
Roto-iti-kite-a-Ihenga (The little lake discovered by Ihenga). Then he came to
Lake Rotorua and named it Rotorua-nui-a-Kahu (The second big lake of Kahu),
after his father-in-law, Kahu-mata-momoe. The Te Arawa tribes who followed him
settled throughout the region, making good use of the thermal areas for cooking,
bathing and heating, and over the centuries occasionally disputing territory
and warring amongst themselves and with the neighbouring tribes from Waikato
and Tauranga.
The 1820s through to the 1860s were a time of particularly violent turmoil and
warfare for Te Arawa. In 1822, one sub-tribe made the mistake of killing
visiting warriors from the Ngapuhi tribe. Ngapuhi controlled much of Northland,
including the area around Russell, which was New Zealand's first sizeable
European port. This meant that Ngapuhi had access to Europeans and their
technology, especially the new military technology of guns.

A Ngapuhi chief, Hongi Hika, had visited King George IV in Britain in 1820,
helped a Cambridge Professor write a Maori language grammar and then picked up
a few hundred muskets in Sydney on his way home. Hongi Hika used his muskets
and the large number of warriors he could recruit with them to settle various
old scores. In 1823, he came down the coast, up a river and had his men haul
their great big sea-going war canoes kilometres through the bush so that he
could attack Te Arawa's island refuge of Mokoia in Lake Rotorua (centre top of
picture). Te Arawa survived the attack, but their numbers were decimated. In
the 1830s, European missionaries found the region embroiled in violent
conflicts between sub-tribes and complained that their converts were all dying
too quickly. Then, in the 1850s, there was warfare with neigbouring Waikato
tribes after an Arawa warrior murdered a Waikato chief.
British colonial forces fought major battles with Ngapuhi in the 1840s and
invaded the Waikato in the 1860s. So, during the conflict of the 1860s, Te
Arawa allied with the colonial government against their tribal enemies. Because
of this, Te Arawa did not suffer the immense punitive land confiscations that
stripped 'rebel' Maori of their land. They still own a considerable amount of
real estate in the region, most notably Mokoia Island, Mt Tarawera, the
lakeside village of Ohinemutu, and Whakarewarewa - a spectacular thermal area
with a thriving Cultural Centre and Arts & Crafts Institute, where they are now
perhaps the most visible face of Maori culture in the New Zealand tourism
industry.
Development

Tourism fuelled development. Queen Victoria's son, Prince Alfred, set the trend
in 1870 when he visited the Pink and White Terraces, bathed in hot springs for
their health-giving properties, and enjoyed Maori feasts and cultural
performances. It's pretty much continued that way ever since, in spite of the
1886 eruption of Mt Tarawera that blew apart the renowned Pink and White
Terraces and buried whole villages in metres of ash and mud. Survivors from the
tribe which had guided visitors to the Pink and White Terraces resettled at
Whakarewarewa and quickly got back into the tourism business there. The
eruption had also opened up a new string of craters and thermal activity in the
Waimangu valley that drew tourists - particularly an explosive geyser that
blasted a black mixture of steam and rocks up to 400m in the air (Waimangu
means black water). Even the buried village of Te Wairoa near Lake Tarawera is
now a tourist attraction.
The road from Auckland was completed in 1884 and the railway ten years later.
More accommodation and spa facilities were built and the forests were cleared,
milled and in places replanted in pine trees. Farming didn't do so well until
scientists in the 1930s identified the cobalt deficiency in the soils of
volcanic ash and began to remedy the problem. By that time, vast areas had been
planted in
Radiata pines that grow to maturity here in 25 years. The
Kaingaroa forest between Rotorua, Taupo and the Ureweras was once the largest
man-made forest in the southern hemisphere. Tourism, farming and forestry
remain the principal industries of the Rotorua region, as they are for the
whole of New Zealand really.
Geology

Rotorua's hot springs are powered by the collision between two immense tectonic
plates. Just east of the North Island, the dense sea-floor basalt of the
Pacific plate slides down under the lighter continental crust of the
Indo-Australian plate and continues to push forward while sinking at an angle
underneath the North Island. When the sinking Pacific plate reaches a depth of
about 80 km, it melts, and great streamers of red-hot lava come pushing their
way up to the surface. A particular feature of New Zealand's bit of crust is
that it is not very thick, at about 15 - 20 km as opposed to the normal 35 - 45
km, so the effect of the rising magma is intensified. The Taupo Volcanic Zone
follows the line where the descending plate hits 80 km down and the hot stuff
comes up. This line actually extends under the sea all the way past Tonga to
the equator, and is part of the 'Ring of fire' that encircles the Pacific.
The volcanoes of the Phillipines and Japan, Mount St Helens in the USA, and the
earthquakes of California are all part of this ring.
Most houses and businesses seem to have bores going down to tap the hot water
for mineral pools and for heating. There were so many at one time that the
water table dropped and thermal features such as the geysers at Whakarewarewa
became less active. In the last few years, the city council has limited the use
of bores and the water table has risen again. The geysers and bubbling mud
pools are going strong, not just at Whakarewarewa, but also sometimes
unexpectedly in suburban lawns and city parks with spectacular results. Most
of Rotorua also smells strongly of hydrogen sulphide. It can accumulate in
basements, especially by coming through faulty bores, and a few people have
died from it over the years, but it's rated as harmless to tourists.
Thermal Attractions
Waiotapu is about 20 km south of Rotorua on the way to Taupo. Busloads
of tourists converge at the Lady Knox geyser near here at 9:30 every morning
for the 10:00 eruption of the geyser (buy your tickets at Waiotapu first and
come early to get a carpark, a seat and an unobstructed view - it's extremely
popular!). It's so regular because the guides trigger it with cakes of soap.
In colonial days, prisoners washing their clothes in the hot pool discovered
this effect. I imagine it was fairly startling for them at the time. A cairn of
rocks has since been built over the pool to focus the eruption and a nice layer
of deposited sinter makes it look fairly natural. It blasts up to about 30m at
first, and then plays for up to an hour at 5 - 10 m (pictured).

Waiotapu (Sacred waters) is my favourite attraction because of the magnificent,
multi-hued, bubbling, steaming and wildly colourful Champagne Pool. It's 60m
across, 60m deep, bubbling with carbon dioxide, and loaded with everything from
dissolved gold and silver to silica and antimony. The sinter terraces that
drain the run-off are huge, but only a faint echo of what the Pink and White
Terraces must have been like. Mud pools, hot pools and old craters can be
interesting but a trifle drab at times. The Champagne Pool is vibrant.
Waimangu Valley is around 15 km south of Rotorua off the Taupo road.
Brought to life by the 1886 Tarawera eruption, this valley is the greenest and
most natural of the thermal areas. It boasts the 'world's largest hot spring'
and the delightfully blue Inferno Crater Lake, as well as other springs and
terraces on about 4 kilometres of trail through native bush. At the bottom of
the valley, you can also do an informative and scenic half-hour cruise on Lake
Rotomahana under the looming bulk of Tarawera. It's usually uncrowded and
peaceful and they lay on a bus back up the valley.
Whakarewarewa is close to the city, and is its premier attraction. It
combines geysers, springs, terraces, craters and bubbling mud pools with
highly-skilled displays of Maori culture and crafts. It's very popular.
Tikitere, or Hell's Gate, is to the east of Lake Rotorua on the way to
Whakatane. It's predominantly boiling mud, steaming rocks and churning
pools of superheated water, and is a little more sombre and atmospheric than
other areas. It has a nice new spa area where you can slather yourself in mud
and soak out any stress. There are peacocks patrolling the tearooms there, so
watch out underfoot when you come through.
Kuirau Park is in the city and has mud pools, hot springs and other
attractions. It's quite safe in the busy areas, but it's not a place to venture
into at night. It's also a sensible precaution to avoid secluded areas, as
there have been a few muggings and sexual assaults there.
Polynesian Pools in the city is a popular lakeside complex of heated and
mineral pools. Classic outdoor (or indoor) relaxation in any weather.
Other Attractions
Te Wairoa, the buried village, is close to Lake Tarawera. It's kind of
like a New Zealand Pompei (without the bodies or extensive stonework) and quite
an interesting place for a wander.
Mt Ngongotaha Go up on the gondola on a clear day for a view over the
city and lake. There's a restaurant and cafe at the top, and luge tracks down
the slopes (always exhilarating but a little jarring on the butt in places).
Paradise Valley Springs is a little ways behind Mt Ngongotaha. There are
springs of crystal-clear water set in native bush and stocked with hundreds of
hungry trout. There are also native birds and a few lions. It's relatively
natural and relaxing, but beware the tour bus groups (and the tour buses on the
winding country road)!
Redwood Memorial Grove is just a a short distance from Whakarewarewa.
Giant Californian seqouias were planted here in 1901, and now reach about 55m.
It's a great place for a walk or a bike ride in hot weather.
Tudor Towers Museum & The Blue Baths are set in gardens between the
lake and the city. They show the historic spa facilities that people came to
for their health, and the museum has a fabulous display of Te Arawa taonga
(treasures) that give a real insight into their culture. Take a walk along the
lakeshore (pictured) while you're there.
There are also numerous other attractions, such as farm shows (sheep shearing
and the like), bungy jumping, kiwi displays (the bird), Maori villages and
cultural performances, kayaking, fishing, horse riding, bee and honey displays,
mountain biking and lake cruises. I'm sure there are more every time we go
there. As a tourist town, it's well provided with accommodation, restaurants
and cafes. I like it - especially the hot pools and the intense geology.
