The Hunua Traverse Walk is a challenging full-day hike in the Hunua Ranges Regional Park, south of Auckland, New Zealand. This 18-kilometer trail traverses rugged terrain through native forest, offering panoramic views from ridgelines. The track connects Hunua Falls to Mangatawhiri Reservoir, requiring good fitness levels and navigation skills.

Starting Point (Hunua Falls): From central Auckland, take the Southern Motorway (State Highway 1) south. Exit at Papakura and follow Hunua Road for approximately 20 kilometers. Turn left onto Falls Road and continue to the car park. The drive takes about 50 minutes from Auckland CBD.
End Point (Mangatawhiri Reservoir): From Hunua Falls, return to Hunua Road and head south. Turn left onto Mangatawhiri Road and follow signs to the reservoir car park. This is approximately 15 kilometers from Hunua Falls.
Car Shuttle Required: Because this is a one-way walk, you’ll need to arrange transport. Options include leaving a second vehicle at the end point, using a shuttle service, or arranging pickup with friends or family. Some tramping groups coordinate car swaps between groups walking in opposite directions.

The Hunua Traverse isn’t your average Auckland day walk. While most people visit the Hunua Ranges for the gentle stroll to the falls, this route ventures deep into the heart of the park where you’ll encounter proper wilderness. The ridgeline sections offer something rare for Auckland: genuine alpine-style walking where you can see for kilometers in every direction.
The track passes through some of the best remaining examples of lowland podocarp forest in the Auckland region. Keep your eyes peeled for kauri, rimu, and the occasional massive puriri tree that somehow escaped the loggers’ saws. These forests are ancient and the birdsong is exceptional. Tui, kereru, and fantail are common, while the lucky few might spot a long-tailed cuckoo in the warmer months.
Here’s where things get real: the Hunua Traverse is not a “follow the crowd” kind of walk. The orange triangle markers are generally well-maintained but you’ll encounter sections where the track becomes faint, particularly in the middle ridgeline portions where it crosses open tussock. A GPS device or downloaded offline map on your phone is essential, not optional.
The track conditions vary dramatically. You’ll walk on everything from well-formed paths to barely-there routes through scrub. Some sections become extremely slippery after rain, and the clay soil in the Hunuas is notoriously treacherous when wet. That steep descent toward Mangatawhiri has caused more than a few unplanned slides on muddy days.
Let’s be honest about the fitness requirement. This walk features relentless elevation change. Just when your legs recover from one climb, another hill materializes. The cumulative elevation gain is roughly equivalent to climbing the Sky Tower three times, except you’re doing it with a pack on your back while navigating rough terrain.
Most trampers complete the route in 6-8 hours, but slower walkers or those stopping frequently for photos and snacks should budget up to 9 hours. There’s no shame in taking your time, but make sure you start early enough to finish with daylight to spare.
The exposed ridgeline sections make this walk particularly weather-dependent. What starts as a calm morning at Hunua Falls can turn into a windswept battle on the ridge tops. The wind can be fierce up there, strong enough to knock you off balance if you’re not prepared.
Summer offers the most stable weather and longer daylight hours, but it also means less water in the streams. Autumn provides spectacular colors and generally settled conditions. Winter and spring can be wet and muddy, though the clarity after a cold front passes makes for stunning photography. Check the MetService forecast before you go and be prepared to postpone if severe weather is predicted.
Carry at least 3 liters of water per person, more in hot weather. There are streams along the route but they’re not always reliable, particularly in summer. Treat or filter any water you take from streams because cattle graze in parts of the ranges and the water quality can be questionable.
Pack more food than you think you’ll need. The energy expenditure on this walk is substantial and bonking halfway through is miserable. High-calorie snacks like nuts, chocolate, and energy bars are your friends. A proper lunch stop on one of the ridgelines is one of the highlights of the walk.

Beyond the obvious (good boots, rain jacket, sun protection), here’s what experienced trampers bring:
The Hunua Ranges are home to a surprising variety of wildlife given their proximity to Auckland. The pest control efforts have made a real difference and native bird populations are recovering. Listen for the distinctive call of the korimako (bellbird) in the forest sections.
The geology of the ranges is fascinating if you’re into that sort of thing. The rocks are predominantly greywacke, the same tough sedimentary rock that forms much of New Zealand’s mountain ranges. The ridgelines show clear evidence of past erosion patterns and the vegetation changes dramatically with altitude and exposure.
This is a serious backcountry walk despite being relatively close to Auckland. People do get into trouble here. The main risks are:
Carry a personal locator beacon if you have one, or at minimum ensure your phone is fully charged. The 111 emergency number works on any available network, even if you’re not a customer of that particular provider.
Yes, but it’s significantly more challenging. Daylight hours are shorter so you’ll need to start very early. The track becomes extremely muddy and slippery, and the ridgelines can be cold and windy. Only attempt this in winter if you’re an experienced tramper with proper gear.
Patchy at best. You might get occasional signal on the higher ridgelines but don’t rely on it. Download offline maps and tell someone your plans before you go.
No, camping is not permitted in the Hunua Ranges Regional Park. This must be completed as a day walk.
There are no easy exit routes once you’re committed to the traverse. The only realistic option is to continue to the end point. This is why proper preparation and honest self-assessment of your fitness is crucial before starting.
No, there are only toilets at the Hunua Falls car park at the start. You’ll need to use the bush if necessary, following Leave No Trace principles.
No, dogs are not allowed in Auckland regional parks to protect native wildlife.
Much quieter than the short walks around Hunua Falls. You might see a handful of other trampers on a weekend but it’s possible to have long sections entirely to yourself.
Most people walk from Hunua Falls to Mangatawhiri because the navigation is slightly more straightforward and you encounter the best views when you’re still fresh. The track is challenging in either direction.
The Hunua Traverse caught me off guard. I’d expected a pleasant bush walk, maybe some decent views, but nothing prepared me for the way my legs would feel after climbing what seemed like the hundredth hill.
We started early from the Hunua Falls carpark, the morning air still cool and damp. The first section wound through dense native forest, all nikau palms and tree ferns creating a green canopy overhead. The track was well-marked but relentlessly undulating. Just when I thought we’d finished climbing, another ridge appeared.
Around midday, we emerged onto an exposed ridgeline. The wind hit us immediately, but the view across the ranges made every step worth it. Layer upon layer of bush-covered hills stretched toward the Firth of Thames, and I could see both coasts in the distance. We sat on the tussock grass eating squashed sandwiches, watching a hawk circle below us.
The descent toward Mangatawhiri was brutal on the knees. The track turned into a steep, loose scramble in places, and I was grateful for my poles. My water ran low with about three kilometers to go, which made for an uncomfortable finish.
By the time we reached the end point, I’d been walking for nearly seven hours. My shirt was salt-stained, my boots muddy, and I had several new blisters. But standing there, looking back at the ranges we’d crossed, I felt genuinely accomplished. The Hunua Traverse isn’t the easiest day walk in the Auckland region, but it might be one of the most rewarding.
