Mick Keane
My name is Mick Keane, and I am the owner of Sprayer Testing NZ, based in Blenheim.
I bring over 20 years of international, hands-on experience in sprayer operations, performance enhancement, development, maintenance, and repair to every job.
Driven by a commitment to sprayer optimization and sustainable spraying practices,
I established the South Island’s only independent, GrowSafe-certified sprayer calibration and optimization service.
This independence ensures growers receive unbiased, technically robust assessments of their spraying equipment.
Sprayer Testing NZ uses cutting-edge European diagnostic technology and advanced testing protocols to deliver industry-leading sprayer optimization outcomes.
By combining technical precision with deep industry knowledge, your spraying equipment is tuned to operate at maximum efficiency, with our calibration processes designed to meet and exceed New Zealand’s highest testing standards for spray delivery and distribution.

A Patternator session is designed to measure and optimise the spray distribution pattern from your sprayer. During the session, we use a patternator to assess how evenly your sprayer applies liquid along the target surface.
-
This process allows us to:
-
Identify and correct over- or under-application zones at various heights and across rows.
-
Adjust nozzle positions and select appropriate nozzle sizes to ensure an even distribution.
-
Advise on optimal spray pressure, nozzle spacing, and working height.
-
Improve spray efficiency, reduce chemical wastage and drift, and promote more effective crop protection.
-
We can run a drone to see the aerial view of the sprayer running.
-
The nozzle tester can check individual nozzles with an accuracy of 1%. If you would like this service included, please let us know in advance so we can allow sufficient time for it during your session.
