In the heart of the Waikato there’s a multimillion-dollar industry based on a gnat. Glowworms are big business, attracting well over half a million people a year to Waitomo and prompting some to shift from working the land above ground to commercialising the creatures below it. But keeping the caves and their thousands of tiny performance artists in good health requires round-the-clock care.

After the deluge

In the first week of March, a low began to crawl across the Tasman Sea, bringing a humid northerly airstream to the North Island. A warm front swept down, pushing heavy rain ahead of it. On the Coromandel Peninsula, uplift over the ranges made the rain torrential.
