Helicopter into Kaweka, Raft out to Thermal Pools: A Three‑Day Upper Mohaka Expedition

Upper Mohaka – Grade 3 takes you into the heart of the Kaweka Forest Park in New Zealand's Hawke's Bay Region. For three days you helicopter into a remote put‑in above the Mangatanguru confluence and raft out to State Highway 5, moving through clear river runs, thermal hot pools, and native forest. On day one the helicopter slices across the Kaweka Mountain Range, depositing your group where greywacke ridges drop to fast, clear water. Guides unpack rafts and you glide three hours downstream to a riverside campsite tucked beside steaming natural hot springs. The river here carves through stony channels and occasional braided shelves, offering Grade 3 rapids that demand attention without overwhelming casual paddlers. Between eddies you can wade for trout, swim in glassy pools, tramp short forest tracks, or ease into a thermal soak beneath beech and kanuka. Day two widens the corridor: forest species shift from mountain beech to mixed podocarp pockets and pockets of regenerating farmland, while river dynamics alternate playful rapids and long float sections. Guides reestablish camp, cook over gas and open fire, and share local lore about the land and its relationship to local iwi. Nights are river-dark; stars spill over the ranges and conversation centers on river lines and fishing stealth. On the third morning you roll rafts for the final run to the SH5 bridge takeout. Lunch is packed on the river and the team shuttles you back to base. The trip can be slowed for anglers who want extra time to stalk trout or customised to include additional hiking and remote access by helicopter. What sets this expedition apart is the blend of helicopter access, multi-day river travel, and the thermal springs—few raft trips let you finish a day with a hot dip under native forest canopy. The geology of the Kaweka ranges—exposed greywacke and volcanic outcrops—frames every bend, while endemic birds like tui and fantail add soundtrack. With a minimum age of seven, the adventure balances family accessibility with genuine wilderness character. Practical notes: the Upper Mohaka is seasonally sensitive; higher flows in spring make rapids livelier, and late-season low water can require alternative plans. Operators emphasise safety—no alcohol during trips, strict weight and chest limits, and basic rafting instruction from guides. For travellers based in Napier or staying at local lodges, this helicopter-in, raft-out route is a singular way to experience Hawke's Bay's wild interior. Bookings are made through the operator's FareHarbor page; flights and river logistics are coordinated in advance. Expect thorough gear checks and experienced guides who run safety briefings and river technique clinics. Bring an open schedule—this trip rewards slow decisions, extra casts, and unhurried swims when the river and weather allow and family groups.
