The History of the Caves

Discovery

The caves were first explored in 1887 by Māori Chief Tāne Tinorau and English surveyor Fred Mace.

Using a small raft made from flax, they entered the cave system and discovered the extraordinary glowworms that illuminated the cavern ceilings. Their exploration led to the development of one of New Zealand's oldest tourism attractions.

Today, descendants of Tāne Tinorau remain involved in the stewardship and cultural heritage of the caves.

Geological Formation

The Waitomo cave system began forming approximately 30 million years ago when much of the region lay beneath the ocean.

Over millions of years:

• Marine organisms formed thick limestone deposits

• Rainwater slowly dissolved the rock

• Underground rivers carved tunnels and chambers

• Mineral-rich water created spectacular formations

This process produced:

Stalactites

Formations hanging from cave ceilings.

Stalagmites

Rock columns growing upward from the cave floor.

Flowstones

Smooth mineral deposits resembling frozen waterfalls.

Many formations continue to grow today, although at an extremely slow rate.

The Glowworms

The caves are home to Arachnocampa luminosa, a species found only in New Zealand.

How They Glow

Glowworms produce a blue-green bioluminescent light from their tails to attract insects into sticky silk threads suspended from cave ceilings.

The result is a breathtaking display that resembles:

• A starry night sky

• Constellations underground

• Thousands of tiny lanterns

The darker the cave, the more dramatic the glow becomes.

The Glowworm Boat Ride

Environmental Conservation

The cave ecosystem is extremely delicate.

Conservation measures include:
