P contaminated properties

If you wish to report a suspected clandestine drug laboratory or clan lab you should contact the police directly.

Clandestine drug laboratories 

Police notify Council of all clandestine drug laboratories discovered within the Tauranga and Western Bay areas.

Council must ensure that the information provided by the police is available to people veiwing a property's file, or applying for a land information memorandum or LIM report.

We also have an obligation to make sure that all dwellings in the city are safe and sanitary for human habitation and to ensure that:

  • the effects of any possible contamination are dealt with
  • the information that is placed on the building file has minimal effect on the property in the long term and
  • no one occupying the dwelling currently, or in the future, is at risk.

When a clandestine drug laboratory has been identified Council requires the property owner to arrange sampling and analysis to be done by a certified laboratory, to determine the level of contamination.

If the level of contamination exceeds 1.5ug/100sqcm, the property owner needs to have remedial work done by a qualified agency to decontaminate the site and provide a report, including additional sampling, showing the property is no longer contaminated. 

A copy of the police notification, the results of the initial sampling, details of cleaning and decontamination undertaken and a copy of post-decomtamination sampling results will be placed on the building file. 

For further information on clandestine drug laboratories please contact Council's environmental health officer.

Properties contaminated by methamphetamine

The New Zealand Standard NZS 8510:2017 recommends the following levels for methamphetamine contamination from use in properties are:

  • 1.5ug/100sqcm in high use areas
  • 3.8ug/100sqcm in limited use areas

High use areas are those areas in a property that can be easily accessed and is regularly used by adults and children. Limited use areas are areas likely to be accessed only by adults and for short periods of time. This includes crawl spaces and wall cavities.
