KARAMEA TO HAAST
COMMITMENT TO SAFETY
Drilling by it's very nature is a hazardous industry. Westmere Drilling is committed to the belief that hazards which cannot be eliminated must be controlled and risks must be minimized. When Ken purchased his first drilling rig in 1994, he made a promise to his wife: "Safety would always come before profit." All staff learn our catchphrases early in their inductions - 'Safety before profit', and 'Do it once, do it properly.'
Ken and Judith's commitment to safety was paramount when developing and tutoring Tai Poutini Polytechnic's Driller's Offsider Programmes from 2009 - 2013.
