Reducing Sick Days Through Better Workplace Hygiene

Every sick day costs New Zealand businesses money through lost productivity, reduced efficiency, increased workloads for other staff, and lower workplace morale. While occasional illness is unavoidable, many workplace-related illnesses spread because of poor hygiene practices, contaminated surfaces, and inadequate cleaning routines.

From shared desks and lunchrooms to washrooms and high-touch surfaces, offices can quickly become breeding grounds for bacteria and viruses if proper workplace hygiene standards are not maintained. In fact, research consistently shows that improving workplace cleanliness and hygiene can significantly reduce absenteeism and improve employee wellbeing.

For New Zealand businesses, investing in better workplace hygiene is no longer simply about appearances — it is an essential part of protecting staff health, maintaining productivity, and creating a professional environment that employees and customers trust.

This guide explains how workplace hygiene affects sick leave, the hidden hygiene risks many businesses overlook, and practical strategies NZ workplaces can implement to reduce illness-related absences.

Why Workplace Hygiene Matters More Than Ever

Many illnesses spread through everyday workplace contact. Shared equipment, communal kitchens, meeting rooms, bathrooms, and reception areas all contribute to the spread of germs throughout a business.

When one employee becomes sick, it can quickly impact entire teams.

Common workplace-transmitted illnesses include:

• Colds and influenza

• Gastro bugs

• COVID-19 and respiratory viruses

• Foodborne illnesses

• Skin infections

• Allergic reactions caused by poor cleanliness

Poor hygiene standards can lead to:

• Increased employee sick leave

• Lower staff morale

• Reduced productivity

• Negative customer impressions

• Higher cleaning and maintenance costs

• Greater health and safety risks

For businesses operating in customer-facing industries such as hospitality, healthcare, retail, education, and offices, workplace hygiene directly affects both employee wellbeing and brand reputation.

Recent reporting has highlighted just how significant workplace illness has become for New Zealand businesses. A study covered by RNZ found that increasing sick leave is now costing the New Zealand economy an estimated $4.17 billion annually. The research showed that Kiwi workers are taking more sick days than in previous years, with illness, stress, burnout, and workplace health concerns all contributing to rising absenteeism. For employers, this reinforces the importance of proactive workplace hygiene strategies. While businesses cannot eliminate illness entirely, maintaining cleaner, healthier workplaces can play a major role in reducing the spread of germs, improving employee wellbeing, and minimising avoidable sick leave across teams.

The Real Cost of Sick Days for NZ Businesses

Many businesses underestimate the financial impact of employee illness.

The true cost of workplace absenteeism includes:

Lost Productivity

When employees are absent, work slows down. Other team members often need to cover responsibilities, which can reduce efficiency across the business.

Increased Staffing Costs

Businesses may need to:

• Pay overtime

• Hire temporary staff

• Delay projects

• Redistribute workloads

Lower Workplace Morale

Frequent illness can create stress for remaining employees and contribute to burnout.

Customer Service Impacts

Reduced staffing levels often lead to:

• Slower response times

• Service delays

• Lower customer satisfaction

Long-Term Health Risks

Poor workplace hygiene can contribute to recurring outbreaks of illness that affect business operations over extended periods.

For many NZ businesses, improving hygiene practices is one of the simplest and most cost-effective ways to reduce these risks.

How Germs Spread Around the Workplace

Many workplace illnesses spread through high-touch surfaces and shared spaces.

Common High-Risk Areas Include:

Shared Keyboards and Mice

Employees frequently touch shared devices throughout the day without sanitising them.

Door Handles

Door handles are among the most frequently touched surfaces in any workplace.

Kitchen Areas

Communal kitchens often contain bacteria from:

• Shared fridges

• Microwaves

• Benchtops

• Kettles

• Coffee machines

Bathrooms and Washrooms

Poorly maintained washrooms significantly increase the spread of germs and bacteria.

Meeting Rooms

Shared desks, tables, phones, and presentation equipment can all harbour bacteria.

Reception Areas

Customers, couriers, and staff all interact with reception surfaces throughout the day.

Without proper cleaning and sanitising protocols, bacteria and viruses can remain on surfaces for hours or even days.

The Difference Between Cleaning, Sanitising, and Disinfecting

Many businesses use these terms interchangeably, but they are not the same.

Cleaning

Cleaning removes dirt, dust, and debris from surfaces.

This is usually done using:

• General cleaners

• Soap and water

• Microfibre cloths

Cleaning alone does not necessarily kill germs.

Sanitising

Sanitising reduces bacteria and germs to safer levels.

Sanitisers are commonly used in:

• Kitchens

• Food preparation areas

• Shared office equipment

Disinfecting

Disinfecting uses chemicals designed to kill viruses, bacteria, and pathogens.

Disinfecting is especially important for:

• High-touch surfaces

• Bathrooms

• Healthcare settings

• Shared equipment

An effective workplace hygiene strategy uses all three methods appropriately.

Signs Your Workplace Hygiene Standards Need Improvement

Many hygiene issues are not obvious until employees begin getting sick more frequently.

Common warning signs include:

• Staff frequently catching colds or flu

• Lingering odours in kitchens or bathrooms

• Dust accumulation on surfaces

• Overflowing rubbish bins

• Dirty shared equipment

• Soap or sanitiser dispensers regularly empty

• Employees complaining about cleanliness

• Increased pest activity

• Mould or moisture issues

Ignoring these warning signs can lead to larger workplace health issues over time.

Creating a consistent and practical cleaning routine is one of the most effective ways businesses can improve workplace hygiene standards long-term. Without a structured system in place, important cleaning tasks are often missed, supplies run low, and hygiene standards become inconsistent across teams and shared spaces. For businesses wanting to build a more effective cleaning programme, our article NZ Office Cleaning Schedule Guide: How to Create a Cleaning Routine That Works provides practical advice on developing daily, weekly, and monthly cleaning schedules that support healthier, more productive New Zealand workplaces.

Proven Ways to Reduce Sick Days Through Better Workplace Hygiene

1. Focus on High-Touch Surface Cleaning

High-touch surfaces should be cleaned and disinfected more frequently than low-traffic areas.

Key surfaces include:

• Door handles

• Light switches

• Phones

• Shared desks

• EFTPOS machines

• Kitchen appliances

• Bathroom fixtures

Implementing a regular sanitising schedule significantly reduces the spread of germs.

2. Improve Hand Hygiene Across the Workplace

Hand hygiene remains one of the most effective ways to reduce illness transmission.

Businesses should provide:

• Hand sanitiser stations

• Antibacterial hand soap

• Paper towels

• Clear hygiene signage

Encourage employees to:

• Wash hands regularly

• Sanitise after shared equipment use

• Stay home when sick

Touch-free dispensers can also improve hygiene standards while reducing cross-contamination.

3. Upgrade Washroom Hygiene Standards

Washrooms strongly influence both employee health and workplace perception.

A poorly maintained washroom can spread bacteria rapidly throughout a workplace.

Businesses should ensure:

• Soap dispensers are always stocked

• Paper towels are replenished

• Toilets are disinfected regularly

• Floors are cleaned daily

• Bins are emptied frequently

Using high-quality commercial washroom supplies improves both hygiene and user experience.

4. Use Colour-Coded Cleaning Systems

Cross-contamination is a major issue in many workplaces.

Colour-coded cleaning cloths and equipment help prevent bacteria spreading between areas.

For example:

• Red = toilets and bathrooms

• Blue = general office areas

• Green = kitchens and food preparation

• Yellow = medical or sensitive areas

This simple system can dramatically improve hygiene control.

5. Improve Air Quality and Ventilation

Poor ventilation contributes to the spread of airborne illnesses.

To improve indoor air quality:

• Open windows where possible

• Maintain HVAC systems

• Replace filters regularly

• Use air purifiers if necessary

• Reduce moisture build-up

Better airflow helps reduce airborne contaminants and creates a healthier work environment.

6. Create a Workplace Cleaning Schedule

Consistency is critical.

Many businesses only react to hygiene issues after employees become sick.

A structured cleaning schedule ensures hygiene standards are maintained daily.

Your cleaning schedule should include:

• Daily cleaning tasks

• Weekly deep cleaning

• Monthly maintenance checks

• High-touch surface sanitising frequency

• Supply restocking procedures

Clear accountability helps ensure tasks are completed properly.

7. Choose the Right Cleaning Products

Not all cleaning products are suitable for commercial environments.

Businesses should choose products that are:

• Effective against bacteria and viruses

• Safe for staff

• Suitable for workplace surfaces

• Environmentally responsible where possible

Many NZ businesses are now switching to eco-friendly cleaning products that support sustainability goals without compromising hygiene standards.

Persistent workplace odours can also be an early warning sign that hygiene issues are not being properly addressed. Even after regular cleaning, unpleasant smells can linger due to hidden bacteria, poor ventilation, mould, dirty carpets, drains, or contaminated soft furnishings. These underlying problems not only affect employee comfort and customer perception but may also contribute to poor indoor air quality and the spread of germs. For businesses wanting to identify the root causes of lingering workplace odours, our article Why Does Your Office Still Smell Bad After Cleaning? Hidden Causes & Proven Solutions for New Zealand Workplaces explores common causes and practical solutions for creating fresher, healthier office environments.

8. Encourage Employees to Take Hygiene Seriously

Even the best cleaning systems fail if workplace hygiene culture is poor.

Businesses should encourage employees to:

• Clean shared desks

• Wipe down equipment

• Wash hands regularly

• Dispose of rubbish properly

• Report hygiene issues quickly

Creating a culture of cleanliness helps reduce workplace illness long-term.

Environmentally responsible cleaning solutions can support workplace wellbeing while helping businesses reduce waste.

Common Workplace Hygiene Mistakes Businesses Make

Only Cleaning Visible Dirt

A workplace that looks clean may still contain contaminated surfaces.

Inconsistent Cleaning Schedules

Cleaning standards often decline during busy periods.

Consistency is essential.

Using Incorrect Products

Some products:

• Damage surfaces

• Fail to disinfect properly

• Leave harmful residue

Ignoring Shared Equipment

Shared devices are among the highest-risk contamination points.

Running Out of Hygiene Supplies

Empty soap dispensers or sanitiser stations undermine workplace hygiene efforts immediately.

Creating a Healthier Workplace Culture

Reducing sick days requires more than cleaning alone.

Businesses should combine:

• Good hygiene practices

• Clear policies

• Employee education

• Proper supplies

• Regular maintenance

Small improvements across multiple areas can lead to significant long-term reductions in illness-related absenteeism.
