    Abstract This report presents the results of the third survey of sediment
    quality and benthic community health at five subtidal sites in the
    Porirua Harbour. These sites were sampled November 2008.
    Consistent with the results of the 2004 and 2005 surveys,
    concentrations of total copper, lead and zinc are above 'early
    warning' sediment quality guidelines in the subtidal
    sediments of the Onepoto Arm of Porirua Harbour.
    Concentrations of the other metals analysed are currently
    below guideline levels in the Onepoto Arm, as are the
    concentrations of all metals in the subtidal sediments of the
    Pauatahanui Arm.
