Understanding the Running Costs of a Swimming Pool in New Zealand

Owning a swimming pool is a dream for many Kiwi homeowners, offering endless fun and relaxation during our warm summers. However, before taking the plunge, it’s essential to understand the ongoing costs of maintaining a pool in New Zealand. From electricity to water usage, chemicals, and upkeep, the costs can add up. Here’s a breakdown to help you budget effectively.

Power Costs: Keeping Your Pool Running

One of the biggest ongoing expenses for a pool is electricity. Your pool pump, which helps circulate and filter the water, typically runs for 6–8 hours per day in summer and less in winter.

• Energy Costs: According to Genesis Energy, pool pumps can add around $80–$150 per month to your power bill, depending on usage and the efficiency of your system.
• Heating: If you have a heated pool, the costs increase significantly. Electric heat pumps are common in New Zealand, with running costs ranging from $500–$1,500 per year, depending on pool size and location. Solar heating options can reduce this cost, with providers like Sunlover Heating NZ offering alternatives.

Water Costs: Keeping It Topped Up

Evaporation, backwashing filters, and splashing mean you’ll need to top up your pool regularly.

• On average, pools lose around 2–3% of their water per week due to evaporation, according to Watercare NZ.
• Water top-ups depend on your region’s water metering system. In places like Auckland, where water is metered, you’ll pay per litre used, adding extra to your annual running costs.

Chemical Costs: Keeping the Water Safe

Maintaining the right water balance is crucial to keeping your pool clean and safe for swimming. The cost of pool chemicals can vary depending on your pool size, the weather, and how frequently you use it.

• Chlorine/Sanitiser: Expect to spend around $300–$800 per year on chlorine products.
• pH Balancers & Other Chemicals: Testing kits, pH adjusters, and algaecides add an additional $100–$300 annually.
• Stores like Pool & Spa Warehouse NZ and Swimart NZ offer bundles that may save money in the long run.

Maintenance & Repairs: Keeping It in Top Shape

Routine maintenance is key to ensuring your pool lasts for years to come.

• Regular servicing costs between $50–$150 per visit if done by a professional. DIY alternatives include using robotic pool cleaners, like those from Maytronics NZ, which can save money over time.
• Pool lining, pumps, and filters may need replacement every 5–15 years, costing anywhere from $500 to $5,000 depending on what needs upgrading.
• If you have a saltwater pool, the salt chlorinator may need a new cell every 3–5 years, which can cost around $300–$800.

How to Save on Pool Running Costs

There are smart ways to reduce swimming pool costs in New Zealand:

✅ Use a pool cover – This helps prevent evaporation, reducing water and heating costs. Suppliers like Shade Systems NZ offer good options.
✅ Upgrade to an energy-efficient pump – Check out EcoPump NZ, which specialises in low-energy pool pumps.
✅ Use a robotic pool cleaner – Instead of paying for regular manual cleaning, an upfront investment in a robot cleaner can pay off.
✅ Consider solar heating – Reduces heating costs significantly, especially in sunny regions like Auckland or Tauranga.
✅ Monitor chemical levels regularly – Avoid excessive chemical use by testing your pool frequently with test strips or digital testers.

While having a swimming pool in New Zealand is a fantastic addition to any home, it’s important to be aware of the ongoing costs. By understanding and managing these expenses wisely, you can enjoy your pool while keeping costs under control.
