    Abstract Please note: This report replaces an earlier version having
    discovered an error in the original report.

    This report summarises baseline sampling undertaken in the tidal
    reaches of the Waiwhetu Stream in January 2009 before extensive
    flood control and contaminated sediment remediation work
    commences by Greater Wellington Regional Council and Hutt City
    Council.

    A second survey is programmed for January 2011 once the
    remedial work has been completed. Sampling methods were
    based on the National Estuary Monitoring Protocol and recent
    extensions, with the results providing baseline data to compare
    future changes against.

    Results are also compared to broad and fine scale indicators
    of chemical and biological condition to help relate 'estuary'
    condition to the key issues of eutrophication, sedimentation,
    toxicity and habitat loss.
