Mould Testing — Samples From Anywhere in New Zealand

Expert mould analysis by qualified Mycologists and Occupational Hygienists — courier a sample to our Hamilton lab from anywhere in NZ

Scaada NZ provides specialist mould testing and laboratory analysis to clients across the entire country. Whether you're a homeowner in Auckland, a building consultant in Wellington, a remediation contractor in Christchurch, or a property professional anywhere in between, you can submit samples by overnight courier to our Hamilton laboratory and receive McCrone-certified analysis with electronic reporting.

How to send us a sample

Mould testing from anywhere in New Zealand in four steps. Collect a sample, courier it to our Hamilton laboratory, and receive a McCrone-certified report — typically within three business days.

  1. 1

    Get a sampling kit

    Order Air-O-Cell spore traps, Bio-Tape lifts and cavity sampling tubes from our Hamilton stock, or use your own. Homeowners can request a simple tape-lift kit; consultants and assessors order in volume.

  2. 2

    Complete the chain-of-custody form

    Every sample travels with a chain-of-custody record, so your result stays defensible for insurance, tenancy and remediation purposes. Download the chain-of-custody form (PDF).

  3. 3

    Courier it to our lab

    Send your packaged samples and the completed form by overnight courier to:

    Scaada NZ
    43 Diomede Glade, Flagstaff
    Hamilton 3210, New Zealand
    022 315 1171

    Samples received Mon–Fri, 8:30am–5:00pm.

  4. 4

    Get your report in 3 business days

    Your report includes genus-level identification, quantitative spore counts and a plain-English summary — analysed to ASTM D7658-17 and D7391-20, and reported against ANSI/IICRC S520 criteria.

Building Material Analysis

Comprehensive analysis of surface samples and bulk building materials for mould identification and quantification. Our McCrone-trained analysts examine samples using brightfield and phase contrast microscopy to ASTM D7658-17 and ASTM D7391-20 methodology, providing detailed identification of mould genera and species present, along with semi-quantitative assessment of contamination levels in line with ANSI/IICRC S520-2024: Professional Mould Remediation.

Sample Types

  • Clear tape lifts and bio-tapes from visible growth
  • Surface swabs and dust samples
  • Black mould identification — distinguishing Stachybotrys from other dark-coloured moulds
  • Gypsum board and plasterboard
  • Timber and framing materials
  • Carpet, underlay, and insulation
  • Wall linings and claddings
Airborne mould spore analysis

Air Quality Testing

Laboratory analysis of airborne spore samples to assess indoor air quality and identify mould contamination sources. Spore trap cassettes capture airborne fungal structures which are then examined microscopically, with results compared against industry guideline criteria including ACGIH (American Conference of Governmental Industrial Hygienists) guidance by our qualified Occupational Hygienists.

What We Provide

  • Spore trap cassette analysis and quantification
  • Indoor vs outdoor comparison to identify contamination sources
  • Genus identification of mould taxa for use in potential health significance assessments
  • Reporting using ACGIH criteria, and results compared with international industry guideline criteria

Interpretation

Results are compared against recognised industry guideline criteria including ACGIH bioaerosol assessment principles. Elevated indoor counts or different species composition compared to outdoor samples may indicate an indoor mould source requiring investigation.
