Lake Papaitonga's peaceful bush-clad setting belies its bloody past. After the local Muaūpoko tribe attacked a group including Ngāti Toa chief Te Rauparaha, they became a target for reprisal raids by Ngāti Toa. Despite retreating to artificial islands they had built in Lakes Papaitonga and Horowhenua, large numbers of Muaūpoko were killed, and survivors fled to the nearby Tararua Range.
