    Abstract This report presents the findings of sediment monitoring at nine intertidal and nine subtidal sites within Porirua Harbour. This monitoring was undertaken in January 2017 and included assessments of sediment grain size, sediment oxygenation and sedimentation rate. Mean annual sedimentation rates are presented along with depth to the RPD boundary (cm) and percentages of mud, sand and gravel for each of the 18 sites monitored.
