How Much Does It Really Cost to Maintain a Swimming Pool in New Zealand?

Owning a swimming pool in New Zealand is a fantastic way to enjoy the summer months and add value to your home. However, many homeowners don’t realise that the ongoing maintenance costs can add up over time. From pool chemicals to electricity and repairs, it’s important to understand the expenses involved so that you can budget accordingly.

Regular Pool Maintenance Costs

To keep your pool clean and running efficiently, regular maintenance is essential. Here’s a breakdown of the key ongoing costs:

1. Pool Chemicals

Maintaining the right chemical balance in your pool is crucial for keeping the water safe and algae-free. The cost of chemicals varies depending on the size of your pool and the type of system you use.

• Chlorine: $20–$50 per month
• pH balancers & algaecides: $10–$30 per month
• Salt (for saltwater pools): $15–$40 per month

Retailers like Swimart NZ and Pools & Spas Warehouse offer a variety of chemical treatments and maintenance products for different pool types.

2. Electricity Costs

Running a pool pump and filter system is necessary to keep your water clean, but it does contribute to your power bill. The average electricity cost for running a pool in New Zealand depends on factors such as the type of pump and how long you run it.

• Pool pump: $50–$150 per month (depending on use and efficiency)
• Heating system (if applicable): $100–$500 per month (varies by type: heat pump, gas, or solar heating)

If you’re looking to cut costs, consider investing in an energy-efficient pump, such as the models available from Waterco NZ, which can reduce power consumption.

3. Water Costs

Over time, you’ll need to top up your pool due to evaporation, splashing, and backwashing your filter system. Depending on your region and water rates, refilling your pool can cost anywhere from:

• $10–$50 per top-up
• $200–$500 annually (for larger pools)

Some homeowners install rainwater collection systems to reduce their reliance on mains water, helping to cut costs.

Periodic Maintenance and Repairs

In addition to regular upkeep, there are occasional maintenance and repair costs that homeowners should prepare for.

1. Pool Cleaning Services

If you prefer to have a professional service maintain your pool, costs can range from:

• $50–$150 per visit for a standard clean and chemical check
• $100+ per visit for deep cleans, including vacuuming and filter maintenance

Services such as Swimmate Pool Cleaning and The Pool Man offer routine maintenance plans.

2. Filter and Pump Repairs

Your filtration system is a key component of your pool and will eventually require servicing or replacement.

• Pump replacement: $500–$2,000
• Filter replacement: $300–$1,500

Regular maintenance and cleaning of your filters can extend their lifespan and help you avoid high replacement costs.

3. Pool Resurfacing and Repairs

Over time, pool surfaces may require repairs due to wear and tear. Cracks, leaks, or resurfacing the pool can be a significant cost.

• Minor crack repairs: $200–$500
• Pool liner replacement: $3,000–$6,000
• Concrete pool resurfacing: $5,000–$15,000

If your pool is older, planning ahead for these larger costs can help prevent unexpected expenses.

Ways to Save on Pool Maintenance

Although maintaining a pool comes with ongoing costs, there are several ways to reduce expenses:

1. Invest in a Pool Cover – A pool cover can reduce evaporation, minimise debris, and lower heating costs. Products such as those from 4MyPool NZ can help you maintain water levels and reduce chemical use.

2. Use Energy-Efficient Equipment – Upgrading to a variable-speed pool pump can cut electricity costs significantly. Look for models that have a high energy-efficiency rating.

3. Maintain Regularly to Avoid Costly Repairs – Keeping up with small maintenance tasks prevents bigger, more expensive repairs down the line. Regularly checking your pump, filters, and water chemistry ensures the longevity of your pool.

4. Consider a Saltwater Pool – While saltwater pools have higher upfront costs, they can be cheaper in the long run due to lower chemical usage.

Final Thoughts

Owning a swimming pool in New Zealand comes with both financial and time commitments. While ongoing costs can range from $1,500 to $5,000 per year, proper maintenance and smart investments in energy-saving technology can help keep expenses under control. Whether you perform your own maintenance or hire a professional, staying on top of pool care is key to ensuring you get the most enjoyment out of your backyard oasis.
