Mick Keane - Director

My wife and I along with our two children made the leap to NZ from the UK in 2014. Clare is originally from the UK and I am from Southern Ireland. My background is in agriculture, and I have travelled the world operating, developing, servicing and repairing sprayers. Clare’s background is in government roles as well as admin/marketing for our business Sprayer Testing NZ. Combined with my industry knowledge and my passion for sustainability I founded Sprayer Testing NZ LTD. The only independent, GrowSafe-certified Sprayer calibration company on the South Island. We use all the latest diagnostic equipment and processes from Europe to ensure we are meeting the highest standard of calibration/testing in NZ. In a typical week, I will be testing/calibrating Sprayers, mostly in the viticulture industry as well as working alongside Smart Machine as an engineer and in their R&D department. I have a project within our R&D department that could make a huge difference to our industry. Watch this space! When I have free time I love spending time with my family, exploring the great outdoors everything from crazy motorbike adventures, swimming, and trekking to having a relaxing day in the sounds. I am grateful to have the opportunity to work in an industry I am passionate about.
