Last updated October 2026
Karioitahi Beach is a long black sand surf beach on the Tasman Sea, about 7 km west of Waiuku at the southern end of the Āwhitu Peninsula.
Surfcasters and kontiki longliners fish it for kahawai and trevally, mostly south of the surf club towards the Waikato River mouth. It is one of only two Auckland beaches you can drive on, with a free council permit. It is also an exposed west coast beach with rips and undertow, so treat the surf with respect.

The Background
Karioitahi is the official name, set in 1950, although the surf club spells it Kariaotahi and the older form Kariotahi is still seen.
The beach runs along the Tasman Sea between the Manukau Harbour entrance to the north and the Waikato River mouth to the south. The council reserve at 685 Karioitahi Road is the main way onto the sand, and council describes it as a very windy spot.
The black sand is ironsand. The dunes behind the beach built up over about 2 million years from Taranaki and central North Island volcanic material carried down by the Waikato River, and they hold a string of dune lakes.
Since 1969 New Zealand Steel has mined ironsand at Waikato North Head, at the southern end of this coast, for its Glenbrook mill.
Ngāti Te Ata Waiohua are mana whenua here. At their request, and with the Franklin Local Board’s support, council moved in 2024 to cut the speed limit on the beach from 60 km/h to 20 km/h, for safety and environmental reasons.
Surf Life Saving Kariaotahi has looked after the beach since 1969. Its volunteers patrol at weekends and on public holidays from Labour Weekend to the end of the Easter school holidays, a regional lifeguard service covers weekdays over the peak of summer, and the club answers search and rescue callouts all year.
How to Fish Karioitahi Beach
Where and when
A Waiuku local’s advice is that most surfcasters head south of the surf club, about halfway to the Waikato River mouth, where the bottom is clean sand. Further north, around Hamilton’s Gap (a separate access point), there is more foul ground and it is easy to lose a kontiki or rig.
Anglers report the best results on the outgoing tide and over low tide: look for the holes and gutters along the beach, where fish feed in the deeper water.
What to catch and what to use
- Kahawai: the most reported catch along the beach, on surfcasting rigs and longlines.
- Trevally: also taken from the surf along the beach.
- Kontiki and drone longlines: popular here. MPI treats them as shore-based longlining under the set line rules, so check the current rules for hooks and marking before you set.
- Other species: snapper and gurnard are sometimes mentioned for this coast; treat them as a bonus rather than the main target.
What to bring
Bait, berley and rigs from Waiuku on the way out (see below), plenty of sinkers heavy enough to hold in the surf, and warm, windproof clothing: there is little shelter on the beach and the reserve is very windy.
Getting There and Facilities
- Road: Karioitahi Road runs west from Waiuku to the beach reserve.
- Parking and toilets: the reserve has a car park, toilets and changing rooms.
- Driving on the beach: Karioitahi and Muriwai are the only Auckland beaches you can drive on, and only with a council permit. The permit is free and lasts 12 months. You may drive only 3 hours either side of low tide, on the firm sand below the high tide line and off the dunes, and you must carry photo ID and the permit. The beach is a legal road, so road rules apply. Only registered vehicles are allowed: no trail bikes or buggies.
- At the car park: vehicles go on and off the beach at the north and south ends of the car park area. Do not drive on the sand directly in front of the car park, which is the busiest swimming area.
- Speed: council lowered the beach speed limit to 20 km/h from late 2024. Check the signs for where it applies.
- Fires: fires and fireworks are banned anywhere in the reserve, including on the beach. Vehicle access can also be closed in very dry, high fire-risk weather.
- Horses: riders use the beach too, so give them room.
Rules and Safety
- Sea fishing here follows MPI’s Auckland and Kermadec rules. Karioitahi is in Auckland West, where some snapper limits differ from Auckland East. No licence is needed.
- Set netting is banned along this coast (Pariokariwa Point to Maunganui Bluff) to protect Māui dolphins, and drift netting is banned in all New Zealand waters.
- Kontiki and drone longlines count as shore-based longlining. Check MPI’s current set line rules before you set one.
- This is an exposed surf beach with rips and undertow. Three people drowned here within six weeks over the 2021 to 2022 summer, all swimming when lifeguards were not on duty. Do not wade out to cast in a big surf, and swim only between the flags.
- Near the Waikato River mouth the sea can reach the dunes at high tide, so watch the tide if you walk or drive south.
- The beach is a road: watch for vehicles and keep lines, rod spikes and buckets out of their way.
Tackle and Bait Nearby
- DKM Fishing and Marine, 49 Belgium Street, Waiuku: bait, berley, surfcasting and longline rigs and kontiki systems. Its website mostly takes orders online, so check it before you call in.
