Vision, Mission and Values
Raising the status and standards of commercial cleaning in New Zealand.
Training to the science
Our training content is anchored in recognised standards and evidence-based infection prevention (NZS 8134:2021; South Australian Healthcare Cleaning Standard). Our trainers teach and assess for true competency, so you can be confident in providing safe, consistent cleaning that meets the highest expectations.
Credentials, conduct, and accountability
We uphold industry codes and recognised qualifications, helping cleaners building the practical skills, professional behaviours, and strong ethics that raise the standing of commercial cleaners across New Zealand.
Learn, audit, improve and repeat
We use the learn-audit-improve-repeat cycle in everything we do. From initial training and competency assessments to on-site audits and refresher programmes so cleaners and teams continuously build skills, maintain safety, and achieve the highest standards.
