Perched above the Kerikeri River, Rainbow Falls — known in te reo Māori as Waianiwaniwa — announces itself with a thunderous voice. The 27-metre drop throws up a cloud of spray that catches light into shimmering rainbows, giving the waterfall its evocative name and creating a sensory spectacle of sight, sound and scent.
Arrival is part of the pleasure. A well-formed bush walk leads from Kerikeri township into a pocket of native forest where pohutukawa, kanuka and other Northland species frame narrow glimpses of the river. The track is an invitation to slow down: birdsong punctuates the air, ferns carpet the forest floor and the path gradually guides you toward the growing roar of falling water.
When you crest the viewing platform, the scale and drama of Waianiwaniwa become immediately apparent. Water plunges cleanly over a basalt lip into a turbulent plunge pool below; depending on recent rain, the torrent can be delicate and silver or a raw, surging curtain of white. Those spray-filled moments are the best for photographers — a wide-angle shot that captures the waterfall and the scattering rainbows is a classic Kerikeri image.
This is an experience that engages all the senses. The constant percussion of the falls, the cool, damp breeze on your face, and the earthy perfume of wet leaves combine to create a restorative pause from busy travel days. The track itself rewards a gentle, unhurried pace: stop to inspect moss-covered boulders, or simply stand and watch the water reshaping rock in real time.
Practical tips: wear sturdy shoes with good grip, as paths can be slippery after rain; bring a waterproof layer and a camera or smartphone with protection against spray; and consider insect repellent for warmer months. Respect local signage and keep to designated tracks to protect fragile vegetation and cultural sites.
Rainbow Falls is an ideal half-day outing from Kerikeri or a short escape from other Bay of Islands highlights. Whether you come for the photography, the nature therapy, or the simple thrill of witnessing powerful water in motion, Waianiwaniwa delivers a memorable and immersive taste of Northland’s wild heart.
