Sampling sites are located in the Central Waitemata Harbour (CWH), Manukau, Mahurangi, Kaipara, Upper Waitemata Harbour (UWH). Sampling frequency = bimonthly in CWH (Feb, Apr, Jun, Aug, Oct, Dec), trimontly in Mahurangi (Jan, Apr, Jul, Oct) and UWH (Feb, May, Aug, Nov) for some sites and annually for some muddy sites to avoid disturbance. Sampling began in 1987 (not at all sites) and is ongoing, apart from the subtidal sampling in Mahurangi which ceased in 2010. Number of sites = 33 total (note some sites monitored on rotational basis, 2 years on and 5 years off). Extent of site = 9000m2. Number of replicates = 12 per site. Measured variables = Infaunal communities using 500um mesh (species identifed to lowest taxonomic level possible and enumerated, key bivalves measured). Sediment characteristics (grain size, TOC and chlorophyll a). Sampling protocol & QA = Internal, NIWA laboratories.

Quality assurance was imposed on methods. Geographic data used NZTM (LINZ). Temporal data were in NZST. Data collection information: Infaunal core = 150mm tall x 130mm diameter. Seive mesh = 500um. Sediment core = 20mm tall x 20mm diameter.
