NZ’s Best Educated School Cleaners

Kids love a mess…

We’re right behind them, providing a full service to schools including day-to-day cleaning, hard floor care, term break cleaning, windows and more.

With over 500 schools on our roll, and the industry’s best training for our personnel, we are definitely New Zealand’s best-educated school cleaners.

school support

CrestClean understands school cleaning. We have been a major provider of school cleaning services since 1996 and have over 500 customers, including primary, intermediate and secondary schools throughout New Zealand.

“Consistency” is the word that sums up what we believe schools need most from their cleaning provider. That means a consistent level of cleaning, a consistent level of account management and term cleans performed consistently to the required standard on time.

Average staff turnover in the New Zealand cleaning industry ranges between 70% and 120% annually. For long-established institutions and schools that require reliable veteran staff, this raises issues with security and Health and Safety compliance.

At CrestClean, our average tenure is more than five years, which means our personnel have made a career choice and are sticking with it. They’re trained industry experts who have financially invested in their own businesses and know that maintaining excellent customer relationships is critical to their success.

We’re known as New Zealand’s best-educated school cleaners – All our personnel undertake formal training programmes including practical cleaning training, proficiency assessments and annual upskilling throughout their CrestClean careers. Our personnel are trained by The Master Cleaners Training Institute, a respected training organisation that has delivered internationally recognised programmes including courses accredited by the British Institute of Cleaning Science (BICSc).

More than 500 CrestClean cleaners have gained the BICSc Professional Skills Suite Certificate. This course was validated by an NZQA accredited Industry Training Organisation that moderated our course content. Each year we host more than 200 training events for our personnel nationwide. We’ve invested in comprehensive training for all personnel which covers cleaning skills and processes, Health and Safety, and hygienic practices. But it’s important we get the best grades from you — feedback is requested through routine Customer Quality Surveys and our Regional Managers audit our cleaning equipment and personnel biannually to ensure consistency and quality standards are being met.


CrestClean is a Gold Partner to the New Zealand Principals’ Federation and a partner since 2008.

CrestClean offers:

  • Stable and secure workforce of owner-operators
  • A detailed specification for your school cleaning
  • Programmed term cleans
  • Scheduled quality audits
  • Security Vetted personnel in uniforms and photo IDs
  • Vast experience with schools and colleges
  • A very competitive price – value for money

Employment Issues

Employing cleaners directly creates a management headache by having to supervise staff performance and deal with issues like absenteeism. It also exposes the school to risk with Employment Relations issues. Legal processes can make it extremely difficult to get rid of a worker who is not performing.

CrestClean’s cleaning services operate under a contract negotiated with the school. As part of our proposal and quotation we prepare a detailed specification of the duties to be performed. The specification forms the basis of the contract – it includes all cleaning, chemicals and cleaning equipment. The contractual relationship allows the school to organise the cleaning programme in a business-like manner, and maintain a fixed cost financial control with the cleaning operating to a budget as per the contract.

CrestClean is responsible for making sure that the cleaning service operates in accordance with the contract. If the school is unhappy with the service or with the personnel, changes can be made. Because CrestClean’s personnel are self-employed, we are not bound by employment regulations, and changes can be made promptly at the school’s request.

We endeavour to build long-term relationships with our school customers. Our franchisees become valuable ‘team members’ taking good care of the cleaning and hygiene and contributing to the smooth running of the school. Our contract cleaning services include full site management. We take care of school hygiene and presentation requirements without the headaches of supervision or the Employment Relations issues of employing cleaners directly.
