Delivering consistency of health and safety standards in the construction industry.

Measuring Health and Safety

CHASNZ's priority is to improve the lives of workers in the New Zealand construction industry by reducing harm and improving health, safety and well-being.

How we direct our efforts most effectively is often about getting good signals from our business as to what is going right and what needs exta attention.

CHASNZ has made these simple but effective tools available for free use across the New Zealand construction sector. They can be used to gain an independent view as to how health and safety is perceived by the workforce and used as tools to pinpoint risk areas and drive improvement.

Using data to provide insight and action is not a new management science. In many other fields, such as banking, insurance, fraud detection and customer channel marketing, the use of predictive analytics is commonplace. However, in the field of health and safety, we have lagged! Typically organisations and regulators have relied on descriptive analytics such as injury rate trends and simply grouping similar injury types into categories. Albeit, tools we have used to describe what has happened have become more sophisticated, we have evolved from excel graphs to tools such as Power BI.

Guide to Site Access Requirements

This is a collaborative document and has been produced to provide guidance. The aim is to achieve consistent site access standards and safer workplaces for everyone.

Construction sites have known significant hazards associated with them and Under section 36 of the Health and Safety at Work Act 2015, organisations are to provide any information, training, instruction or supervision that is necessary to protect all persons from risks to their health and safety arising from work carried out.

Knowing that people entering our worksites have been trained as well as knowing their competency level are important and basic steps in carrying out an organisation’s duties under the Health and Safety at Work Act.

This guideline has been written to assist all parties who own, control, visit and or work on construction sites.

Tōtika | cross-recognition for Health and Safety pre-qualification in New Zealand

Pre-qualification and assessment of health and safety is an important part of the procurement process. Before Tōtika, there was no common standard for pre-qualification resulting in many proprietary and internal pre-qualification schemes. Creating inefficiency in the supply chain because suppliers had to repeatedly pre-qualify against different schemes and standards. This repeated and duplicated effort wastes time and money for both clients and contractors. There is a strong desire within the industry alike for a common pre-qualification standard and streamlined pre-qualification process; Tōtika has been developed to deliver these outcomes.

Building Frontline Leaders for Safer Work

CHASNZ is working with industry to develop a safety in leadership programme to build the capacity and capabilities our frontline need to lead the safe execution of work.

When completed, the programme will support and recognise the key role our frontline leaders have in making a difference on how work is done and will provide a framework for supervisors to develop leadership skills and capability for more effective on-site safety management.
