Continuous sediment monitoring sites were set up in the lower reaches of the three main tributaries of Te Awarua-o-Porirua Harbour (Porirua Harbour) in 2012/13. The purpose was to quantify the annual and event-based sediment loads to Porirua Harbour, recognising that excessive sediment deposition in the harbour is one of the key issues for estuarine health. These data summarise monitoring results for the period from July 2022 to June 2023. For more information on site set up, instrumentation, data collection and processing, plus how sediment loads and yields are calculated, please refer to Morar & Alberto (2018).
