With laboratories in Lower Hutt, Christchurch, Greymouth and Hamilton, our areas of expertise include solid and liquid fuels testing, rocks and minerals, water, contaminated soils sediments, agricultural soils, air and gaseous emissions. We have a unique range of equipment and, with the support of our in-house laboratory experts, chemists, geologists, and engineers, we’re able to tackle projects others simply shy away from due to lack of capability.

We pride ourselves on providing customer-focused service and prompt turn-around times.

Much of our testing is accredited by International Accreditation New Zealand (IANZ).

Fuel Analysis

We are fully equipped to provide comprehensive analysis of liquid fuels, coal and biofuels. All testing is done to International Standards – ASTM, ISO, BS, or AS, accredited by International Accreditation New Zealand (IANZ).

Biomass Analysis

Our fuels laboratory has the capability to test a huge range of biomass fuels. Testing is conducted to either New Zealand or international standard methods, in-house methods or by creating new methods as required. We have a wide range of equipment and experience to draw on, allowing us to test routine and diagnostic samples. We also have a transitional facility so international biomass can typically be sent directly to the lab without treatment.

We are members of the Bioenergy Association (BANZ) and can analyse and classify fuels to the BANZ guidelines.

Acid Base Accounting

Acid Base Accounting is a tool we use in mine waste management to assess the likely discharge from a mine caused by acid mine drainage. We can conduct the static tests to measure the potential for acid formation and acid neutralisation as well as the longer-term kinetic leaching columns. In addition, we have geochemists, and engineers that can interpret the data and develop waste management plans in line with the emerging world’s best practice.


We frequently test gases from a variety of sources for testing including, gas distributors, landfills, bio-gas manufacturers, mines and ambient air quality tests. Typically, a sample volume of only 200ml is required to complete an analysis using our new Agilent 3000A micro gas chromatograph.

Water Testing

Concerned about the quality of the water or the effects of wastewater? From a simple pH or conductivity test to the analysis of heavy metals, or the growth of E. coli and other coliforms, we offer a comprehensive range of water testing, including both chemical and microbiological analysis, for which our Greymouth-based water testing facility is IANZ accredited and approved by the Ministry of Health.

Asbestos Testing

We offer an available-to-all IANZ-accredited rapid service to analyse building materials for asbestos. We can provide you with explicit instructions for taking your own samples or recommend professionals to survey your building, sample or remove asbestos containing material.
