Owner & Director - Principal Occupational Hygienist
Dr Sage Robinson, COH

Bernadino Ramazzini, the grandfarther of occupational hygiene said in his famous book of 1713 titled Disease of Workers, that ill health from work is the result of two causes: “The first and most potent is the harmful character of the materials they (workers) handle, for these emit noxious vapours and very fine particles inimical to human beings and induce particular diseases; the second I ascribe to certain violent and irregular motions and unnatural posture of the body”. Although now over 300 years old much of this is still true and worker health continues to pose a major challenge in the work environment. As such, New Zealand workers are 10-15 times more likely to die from exposure to agents hazardous to health, than from a workplace safety event.

My passion for occupational hygiene stems from addressing this imbalance and knowing that every day we are improving workers lives through, education of workers, and the assessment and control of workplace health hazards. Coming from a chemistry research background and gaining valuable experience in the semiconductor and petrochemical industries overseas, I joined the Safe and Sound Solutions team in early 2020 establishing the Occupational Hygiene division.

I am Safe and Sound Solutions Principal Occupational Hygienist and a Certified Occupational Hygienist (COH®) with the Australian Institute of Occupational Hygiene (AIOH). I completed my Ph.D. in organic and analytical chemistry from the University of Otago and a Level 8 Graduate Certificate in Workplace health and safety from the University of Newcastle. I am a professional member of both the New Zealand Occupational Hygiene Society (MNZOHS) and Australian Institute of Occupational Hygiene (MAIOH) and the current President Elect of NZOHS, as well as a Professional member of the New Zealand Institute of Safety Management (ProfNZISM).

Senior Occupational Hygienist
Garth Holdsworth, COH

I am a dedicated Occupational Hygienist with a strong educational background and extensive professional experience. Holding a Bachelor of Science degree in Environmental Science, I furthered my education by earning a Postgraduate Diploma in Occupational Health. As a Certified Occupational Hygienist with the Australian Institute of Occupational Hygiene and a Registered Occupational Hygienist with the South African Institute of Occupational Hygiene, I have nearly a decade of experience in the field. My expertise spans various industries, allowing me to offer valuable insights and solutions to occupational hygiene challenges.


In addition to my professional work, I am passionate about education. I have lectured on Occupational Health at several higher learning institutions, earning respect within the academic community for my commitment to knowledge dissemination. Active involvement in professional organizations, such as the New Zealand Occupational Hygiene Society, highlights my dedication to advancing the field. I have served on the council of the society, contributing my expertise to its initiatives. I am committed to promoting a safe and healthy work environment for all. Utilizing my expertise, I work to mitigate occupational hazards and protect the well-being of workers across different sectors.

I am a family-oriented man who enjoys outdoor sports, playing music, reading, and any question that I can’t immediately answer.

Senior Occupational Hygienist
Leon Pretorius, ROH

Over the past 15 years I’ve developed a passion for Exposure Science – an interdisciplinary field that focuses on understanding how people come into contact with various environmental agents, such as chemicals, pollutants, and other hazards. It involves studying the routes, levels, and durations of exposure to these agents and assessing their potential health effects. Exposure science aims to identify and mitigate risks associated with exposure to environmental agents to protect both employees and the public health to ultimately improve their overall well-being.

As a registered Occupational Hygienist, with a BSocSc (Hons) degree in Environmental Management, I have worked across 15 countries assessing and monitoring health hazards and environmental contaminants.  I have extensive experience in Risk Assessments and Exposure Monitoring, with a keen specialisation in Noise Control.

Having experience in management, mentorship, training and teaching, I have worked at various organisational levels to impart leadership and encouragement.

Passion and curiosity are fundamental in my pursuit to constantly learn, share and collaborate with others.

With an array of hobbies and interests, I love trying new things. Outdoor adventures and great coffee is a necessity. Good food, travelling and meeting new people is another bucket-filler for me!

Safety Consultant
Sue MacEwan

My working life initially involved implementing quality management systems for companies in the UK and NZ before I moved to a role in Health and Safety. Since then I have worked as a Health and Safety Advisor in the public and private sector, ranging from civil construction projects in the rural sector to New Zealand Post and New Zealand Police. I have a Diploma in Workplace Health & Safety, I am graded at Professional level by the New Zealand Institute of Safety Management and I am listed on the HASANZ Register of health and safety professionals. I enjoy working with a range of clients on their health and safety journey and finding solutions that are pragmatic, not dogmatic. I believe that keeping people safe and healthy is just part of doing great business.

In my spare time I mostly enjoy dreaming up adventures and getting outdoors with our loopy dog.

Safety Consultant
Brittany Allnutt

Ever since my first encounter with health and safety in the workplace, I have been driven by the potential to change and influence safety decisions, leading to positive outcomes for businesses and individuals. This passion led me to pursue a career in health and safety, obtaining a Level 6 Diploma in Workplace Health & Safety, graded at Professional Level by the New Zealand Institute of Safety Management and am listed on the HASANZ register.

Safety is always at the forefront of my mind, and I find great satisfaction in working closely with individuals and businesses to develop practical solutions that ensure everyone goes home safely at the end of the day. Having previously worked in the construction industry, working at Safe & Sound has given me the opportunity to apply my skills and expertise in diverse fields and gain further knowledge in real world safety practices.

I enjoy the outdoors, being social and staying active, whether it’s out exploring new places with my husband and our pup Herbie, spending time with loved ones, or trying out different restaurants around the city.

Safety Consultant
Josh Wright
Ph.D, BSc(Hons), ProfNZISM, HASANZ

I was born, raised, and educated in Christchurch. I earned a Bachelor of Science from the University of Canterbury, and then a Doctorate in biomedical research from the University of Otago. I subsequently moved to London where I lived for 5 years carrying out HIV and COVID-19 research.

Through my experience working in a research laboratory, where I had constant exposure to hazardous substances, automated machinery, and a high stress working environment, I developed a strong interest in occupational health. Upon returning home to Christchurch live in 2021, I chose to pursue an occupational health career, and joined Safe and Sound Solutions as a Workplace Health and Safety Consultant.

I am family focused. I enjoy fishing, hiking, and travelling with my loved ones. My job is to make sure you and your staff get home safely to the people who matter to you.

I was born in a small town called Tullamore in Ireland. My academic journey began with a focus on Toxicology at Athlone Institute of Technology, I’m currently on the final stretch of my master’s degree in environmental Analysis and Pollution Monitoring. My educational background has provided me with knowledge to assess, identify and understand the effect hazards can have on our health. Before entering the world of Occupational Hygiene my previous experience was in a biopharmaceutical company, where my interest in health and safety first began. My mindset is always to ensure the safety of others comes first before the job, my passion for safety and positive attitude in the workplaces ensures that the job is completed precisely and accurately.

Outside of work I enjoy spending time with family and friends, crocheting and going to the gym.

Founding Consultant
Charles De Lambert

I started my interest in occupational health in the early 1980’s when I trained and worked for the Department of Health and was involved in both public and occupational disease investigation and workplace monitoring of substances, noise and dust.

This passion continued with several compliance manager roles (QA, Enviro and H & S) with large organisations and in 2002 I established Safe and Sound Solutions.

I enjoy helping organisations to define, measure and improve their processes and performance across health and safety, QA and the environmental fields.

I am passionate about the industry and I am an active member of the NZISM and registered on the HASANZ.
