Lake Pateriki (pronounced as /mi/) is a brackish coastal dune lake in northeastern Chatham Island, New Zealand.
Lake Pateriki is a coastal dune lake on northeastern Chatham Island, New Zealand, near the village of Kaiangaroa. Described as brown/yellow or tea coloured, it has a depth of 1.3metres and an area of 134ha. A narrow sand dune separates its northern shore from the Pacific Ocean; this allows for intermittent outflow to the sea and inflow of saltwater, leading to around 50% seawater by volume. Three streams flow into the lake. It is mildly alkaline, like most other lakes on Chatham Island.[1]
