The Waitomo Glowworm Caves attraction is a cave at Waitomo on the North Island of 

New Zealand, known for its populationOf glowworms, Arachnocampa luminosa. This species is found exclusively in New Zealand. They are around the size of an

average mosquito. This cave is part of the Waitomo Caves system that includes the 

Ruakuri Cave and the Aranui Cave.The attraction has a modern visitor centre at the entrance, largely designed in wood. There are organized tours that include a 

boat ride under the glowworms.

The name "Waitomo" comes from the Māori words wai, water and tomo, hole or shaft. The local Māori people had known

about the caves for quite some time before the local Māori Chief Tane Tinorau and an English surveyor, Fred Mace, did

an extensive exploration in 1887Their exploration was conducted with

candlelight on a raft going into the cave where the stream goes underground. This is now the exit for the cave. As they began

their journey, they came across the Glowworm Grotto and were amazed by the twinkling glow coming from the ceiling. As

they travelled further into the cave by poling themselves towards an

embankment, they were also astounded by the limestone formations. These

formations surrounded them in all shapes and sizes.

History

They returned many times after and Chief Taneindependently discovered the upper level

entrance to the cave, which is now the current entrance. Tane Tinorau and his wife Huti, by 1889, had opened the cave to visitors and were leading groups for a small fee. The

administration of the cave was taken over by the government in 1906 after there was an

escalation in vandalism. In 1910, the Waitomo Caves Hotel was built to house the many

visitors.In 1989, the land and cave were returned to the descendants of Chief Tane Tinorau and Huti. They now receive a percentage of the

cave’s revenue and are involved in the management and development of the cave. These descendants encompass many of the

employees of the caves today.

BIOLOGY

The most renowned animal in the cave is the glowworm Arachnocampa luminosa. There are several small underwater lakes that were created by freshwater creeks or brooks. The walls of the caves are covered with a variety of fungi including the cave flower (a distant relation to the genus Pleurotus) that is actually a mushroom-like fungus. The most common animals in the caves are insects. This includes albino cave ants, giant crickets, and of course the glowworms.

CAVE MONITORING

The glowworms of the Waitomo Glowworm Caves are closely guarded by a Scientific

Advisory Group. This group has automated equipment that continually monitors the air

quality especially the carbon dioxide levels, rock and air temperature, and humidity. Data from

this equipment is carefully analyzed by specialist staff. The advisory group uses the

information to establish how the cave should be managed. They determine if and when air flow

patterns should be changed and how many people are allowed to visit the caves each day.

GUIDED TOURS

The Cathedral in the Waitomo Glowworm Caves.The guided tour through the Waitomo Glowworm Caves

brings the visitor through three different levels and begins at the top level of the cave and the Catacombs. The levels

are linked by the Tomo, which is a 16 m vertical shaft made of limestone. The second level is called the Banquet

Chamber. This level is where early visitors stopped to eat and there is evidence of this in the smoke on the ceiling of the chamber. From here it may be possible to link back to

the upper level to see the largest formation called the Pipe Organ but on busy days this area is closed to the public

because the build-up of carbon monoxide may be hazardous.The third and final level goes down into the Cathedral,

demonstration platform, and the jetty. The Cathedral is an enclosed area with rough surfaces, now paved, and is about

18 m high, giving it good acoustics. A number of famous singers and choirs have performed here including Dame Kiri

Te Kanawa.

The tour concludes with a boat ride through the Glowworm Grotto. The boat takes the visitor

onto the underground Waitomo River where the only light comes from the tiny glowworms

creating a sky of living lights.[4]
