Are Landlords Responsible for Pest Control in NZ? What Invercargill Renters Should Know

If you’re a landlord or tenant in Invercargill, chances are pests have popped up on your radar at some point — rats in the ceiling, ants in the kitchen, or wasps around the deck. But when those unwanted guests move in, who should pay to kick them out — the landlord or the tenant?

Under New Zealand’s Residential Tenancies Act and Healthy Homes Standards, landlords must provide a home that’s in a reasonable state of repair and meets building, health, and safety standards. That includes maintaining the property so it doesn’t encourage pest infestations. Tenants, on the other hand, have to keep the place reasonably clean and tidy so they’re not attracting pests with rubbish, clutter, or food scraps.

Think of it like a team effort: the landlord looks after the “shell” of the property, and the tenant looks after the day-to-day living conditions inside it. When either side drops the ball, pests can take advantage.

Understanding Who Pays for Pest Control Under NZ Law

Landlord Obligations under the Residential Tenancies Act & Healthy Homes Standards

Landlords must make sure the property is safe, healthy, and in a reasonable state of repair. That includes fixing things like broken cladding, gaps around doors, damaged rooflines, or rotten floorboards that let rodents or insects in.

If an infestation is linked to:

  • Structural issues
  • Poor maintenance
  • Pests already present at the start of a tenancy

Then pest control is usually the landlord’s responsibility, including arranging and paying for treatment.

Tenant Responsibilities: Cleanliness, Reporting, and Common Sense

Tenants must keep the home reasonably clean and report problems early. If pests show up because rubbish is left out, food is uncovered on benches, or the home isn’t being cleaned regularly, the tenant may be responsible for the cost of pest control.

The same goes for pet-related issues like fleas — if the infestation is caused by how the home is being used, it’s usually the tenant’s responsibility.

When Pest Control Is Usually the Landlord’s Responsibility

Before a New Tenancy and the First Few Weeks

Landlords must provide a home that’s clean and fit to live in at the start of a tenancy. If a tenant moves in and finds ants, rats, or insects that were clearly there beforehand, the landlord should arrange treatment.

Structural Issues, Seasonal Pests, and Maintenance

In Invercargill and Southland, weather changes can drive pests indoors — rodents in winter, flies and ants in summer.

If pests enter because of:

  • Gaps in the structure
  • Broken seals
  • Poor maintenance

Then the landlord is typically responsible for both the repairs and the pest control itself.

When Tenants May Be Responsible for Pest Control Costs

Pest Problems Caused by How the Home Is Used

Now picture a flat in Invercargill’s CBD where rubbish bags sit on the porch for weeks, or where food scraps are left uncovered. Ants and mice appear — and in this case, the infestation is tied to the tenant’s actions.

A tenant may be responsible when pests are caused by:

  • Poor cleaning
  • Incorrect rubbish storage
  • Pets (e.g., fleas)
  • Damage to pest-prevention measures

If the behaviour caused the infestation, the tenant usually pays.

What to Do When It’s Not Clear Who Is Responsible

Start with a Calm Conversation and Check the Tenancy Agreement

Some pest issues land in a grey area — no obvious structural issues and no clear tenant problems. When that happens, the best first step is simply to talk.

Both parties should:

  • Review the tenancy agreement
  • Discuss when and how the pests appeared
  • Consider sharing the cost if it’s unclear

If an agreement can’t be reached, Tenancy Services or the Tenancy Tribunal can provide guidance.
