Hūnua Falls is a 30-metre waterfall on the Wairoa River in Hūnua Ranges Regional Park, about an hour’s drive south of central Auckland. The falls drop over a basalt lava plug into a deep pool framed by native forest and ferns. A short, easy path from the car park reaches the main viewing area in just a few minutes, making it one of Auckland’s most accessible waterfalls. The site is popular for picnics and short walks, and it serves as a trailhead for longer tramps in the ranges. Swimming is not recommended due to serious safety hazards.

About Hūnua Falls
Hūnua Falls sits on the Wairoa River in the western part of Hūnua Ranges Regional Park. The river drops 30 metres over a basalt lava plug that has intruded along a fault line. Volcanic features such as tuff rings and lava bombs are visible in the cliff walls. The falls are a classic horsetail type and look most powerful after rain, when flow increases dramatically.
The surrounding bush is mature native forest with abundant ferns, tree ferns, nīkau and other species. The pool at the base is large and deep. The falls have drawn visitors since Victorian times, when Aucklanders travelled by steamer to Clevedon for day trips. Land in the ranges was purchased by Auckland authorities between the 1940s and 1960 mainly for water supply catchments that still feed major reservoirs serving the city.
The short path from the car park is family-friendly and suitable for most fitness levels. A large photo frame near the viewpoint is a popular spot for pictures. Picnic tables and open grass areas make it easy to linger. The park is rubbish-free, so visitors must take all waste away. Overnight parking for certified self-contained vehicles is available by booking in designated areas.
Hūnua Ranges Regional Park covers more than 14,000 hectares of native forest, the largest such area in the Auckland region. It forms part of Auckland’s water catchment and supports significant biodiversity, including the only mainland Auckland population of kōkako and Hochstetter’s frog.
Walking Tracks from the Hūnua Falls Car Park
The Hūnua Falls car park is the main western gateway to the ranges and the start of several walks. The direct path to the falls viewing platform takes only a few minutes on a well-formed route. The Hūnua Falls Loop Walk (approximately 800 m, 20 minutes) circles the falls for different angles, including lookouts. There is also an Upper Lookout Walk (around 30 minutes return) that climbs for elevated views of the waterfall and surrounding forest.
The standout longer option is the Cossey-Massey Loop Track (8.3 km, about 3 hours). It combines the Cossey Gorge Track and Massey Track, climbing onto ridges with views over reservoirs and through stands of native forest including kauri. The track is metalled in places but has some steeper or rooty sections. Other connecting tracks lead deeper into the park for more experienced trampers. Always check Auckland Council for current track status and closures before setting out.
Tracks can be muddy or slippery after rain. Sturdy footwear with good grip is recommended. The short falls path has some steps that may challenge those with limited mobility; full wheelchair access to the falls base is not available, though car park facilities are more accessible.
Swimming at Hūnua Falls
The deep pool at the base of the falls has long been a popular swimming spot, especially in summer. However, Auckland Council and Safeswim strongly advise against swimming here. The official guidance is “do not swim” or “swimming at the falls is not recommended.”
Hazards include turbulent water, strong currents and rips, cold water that reduces buoyancy and can cause cold-water shock, deep water, slippery rocks, and sudden changes in flow after rain. The site has a history of multiple drowning deaths (several recorded in recent decades, including multiple incidents in single years). It ranks among New Zealand’s more dangerous waterfall swimming locations. Jumping or diving is particularly hazardous due to variable depth and submerged obstacles.
Even if the water looks inviting and clear, conditions can change quickly. There are no lifeguards. Visitors who enter the water do so at their own risk. Safer swimming options exist elsewhere in the Auckland region; check Safeswim for current advice at other sites. The falls remain excellent for viewing, photography and picnicking without entering the water.
Nature, Wildlife and the Regional Park Setting
Hūnua Ranges Regional Park (Te Ngāherehere o Kohukohunui) protects extensive native forest from lowland to the highest mainland Auckland peak, Mt Kohukohunui (688 m). The ecological district holds a high proportion of New Zealand’s native plant species, including many ferns, plus hundreds of fungi species. Birdlife includes tūī, pīwakawaka (fantail), kererū and, thanks to intensive pest control, the rare kōkako with its distinctive call. Hochstetter’s frog, a primitive and silent species, also occurs here but is rarely seen.
The ranges supply much of Auckland’s water through four reservoirs. Large-scale pest control (including recent aerial 1080 operations) continues to protect biodiversity and keep the forest healthy. The area remains free of kauri dieback in key stands, making hygiene practices especially important. Māori traditionally used the ranges for food, timber and as a refuge rather than permanent settlement. European farming and logging were limited by the rugged terrain; water catchment protection has been the dominant land use for decades.
Visitors can expect a peaceful bush setting with the sound of the falls and birdsong. After heavy rain the waterfall is at its most dramatic. Weekdays and winter visits are quieter than summer weekends, when the car park and short tracks can become busy.
Kauri Dieback Hygiene and Park Rules
The Hūnua Ranges contain significant kauri. Although major stands here have remained free of kauri dieback (Phytophthora agathidicida), the disease is a serious threat across Auckland. Cleaning stations are provided at park entries and track starts. Scrub all soil from footwear (and dog paws or bike tyres if applicable), then spray with the disinfectant provided. Stay on formed tracks at all times and do not step into kauri root zones.
Dogs are allowed on a leash on most tracks in the park, including those near the falls, but are prohibited in all campgrounds, near Watercare dams, and in the kōkako management area. Keep dogs under control, on the track, and clean their paws. Check noticeboards and current bylaws for exact zones. The park is smoke-free and rubbish-free. Open fires are illegal. Visible excessive alcohol consumption is prohibited.
What Visitors Often Say
Many people praise the short, easy walk from the large free car park and the impressive 30 m falls, especially after rain when the flow is strong. Families appreciate the picnic tables, toilets and the chance for a quick nature outing close to Auckland. The photo frame and different lookouts are frequently mentioned as highlights.
Visitors often note that the pool looks tempting for a swim but warn of cold water, slippery rocks and the known drowning risks. Crowds and full car parks on fine summer weekends are common complaints, while quieter midweek or winter visits receive higher praise. Some mention ducks near the picnic area and the value of combining the falls with a longer loop track.
