ack on State Highway 3 one travels 16
kilometres south-west of Otorohanga - eight kilometres south on Highway 3, then eight
kilometres off to the right on a well-signposted road - to reach the Waitomo Caves.
These justly
famous caves were formed by underground streams that dissolved passages through the
limestone over vast periods. Water percolating through the limestone became charged with
lime in solution and, dripping down from the cave roof, left behind deposits which
eventually developed into spectacular stalactites and stalagmites. In addition, glow-worms
have colonised a number of areas and the boat journey along the underground river through
the Glow-worm Grotto is unforgettable. The best times to visit are early in the morning,
soon after opening, and late in the afternoon, when there are fewer tourists. Flooding can
cause the glow-worm caves to be closed so, if the weather has been bad, check before
going.Also here is the Waitomo Caves Museum, one of the best small museums in the
country. It has an impressive collection of fossils found in the King Country and its
dioramas are excellent.
More than 160 King Country caves have provided the fossil remains of 53 land and two
marine species of birds, many now extinct. From the predominance of forest dwellers among
these birds, together with the presence of creatures such as land snails, scientists
conclude that from at least 25,000 years ago this area was covered in mixed
podocarp-broadleaf forest. The bones of marine birds such as petrels provide evidence that
before humans arrived with their mammalian predators these birds bred in the inland
forested ranges.
Archaeological evidence also suggests that this is one of the last areas in the North
Island where moa survived. They vanished first from the north and then progressively
became extinct southwards, and simultaneously from the coast towards the interior.
Dr Phil Millener of the National Museum in Wellington compiled a list of extinct
animals which is extensive and sobering 11 moa, a pelican, a swan, two geese, four ducks,
two eagles, a hawk, five rails, an Aptornis, a snipe, an owlet-nightjar, a crow and three
wrens - and these are only birds. Indications are that frogs and a lizard might have
disappeared too.
Back on State Highway 3, and 12 kilometres south of Waitomo Caves tumoff, one reaches
Te Kuiti and, although most of the birds here are common species, the town does hold one
of the country's stranger bird records - a lesser frigate bird was recovered nearby, a
wind-blown tropical stray far from its home range in the central Pacific.
South of Te Kuiti the road forks. State Highway 30 heads south-east towards Mangakino.
Along this road you first pass through farming country, much of which is degenerating into
scrub. Paradise ducks, pied stilts and white-faced herons are all fairly numerous in the
damper areas, although there are periodic shooting drives against the ducks as farmers say
they foul pastures.
A good place to stop is at the Mangaokewa Scenic Reserve which, although a little
rugged, supports a number of birds, both native and exotic. Continuing towards Mangakino
brings you to Kopaki, named for another of our lost birds, the laughing owl - although the
name should more properly be spelt kopake. Also known to some Maori as whekau, this bird
had developed long, sturdy legs for chasing its prey on foot most un-owl-like behaviour.
It ate earthworms, insects, heads and small birds and is best remembered for its 'doleful
shrieks' which were heard incessantly on rainy nights and which were apparently not even
remotely like a laugh.
The range of hills known as the Raepahu Range stretching north-east from Kopaki towards
the Pureora State Forest has a good population of birds, including species that are
rarities elsewhere like the kakariki and the kaka. The kokako and the falcon (karearea)
are also found here but are very scarce.
