Choosing Between a Saltwater and Chlorine Pool in New Zealand
If you’re considering installing a swimming pool in your backyard, one of the biggest decisions you’ll face is whether to go with a traditional chlorine pool or a saltwater system. Both options have their benefits and drawbacks, and the choice ultimately depends on your budget, maintenance preferences, and long-term costs.
To help you make an informed decision, I’ve broken down the pros and cons of each option, with a focus on what works best for New Zealand homeowners.
Saltwater Pools
Saltwater pools are becoming increasingly popular in NZ due to their lower maintenance requirements and gentler water feel. Instead of directly adding chlorine, these pools use a salt chlorinator to generate chlorine through electrolysis.
Pros
✅ Gentler on Skin & Eyes – The lower chlorine levels mean reduced irritation, which is great for families with kids or sensitive skin.
✅ Lower Chemical Costs – You won’t need to buy chlorine regularly, reducing long-term chemical expenses.
✅ Less Harsh on Pool Equipment – Saltwater tends to be easier on swimsuits and pool surfaces compared to traditionally chlorinated pools.
✅ Lower Maintenance – The system continuously produces chlorine, meaning fewer fluctuations in chemical levels.
Cons
❌ Higher Upfront Cost – The initial setup, especially the salt chlorinator system, can be more expensive than a standard chlorine system.
❌ Corrosion Risk – Saltwater is more corrosive to certain pool components, such as metal fixtures and ladders. You may need to invest in corrosion-resistant materials.
❌ Electricity Usage – The chlorinator requires electricity, which means slightly higher power costs.
Where to Buy in NZ
- Pool chemicals and saltwater systems can be found at Para Rubber and Pools & Spas New Zealand.

Chlorine Pools
A traditional chlorine pool is what most people are familiar with. It requires regular chlorine addition, either in liquid, tablet, or granular form, to keep the water clean and bacteria-free.
Pros
✅ Lower Initial Cost – Chlorine pools have a lower upfront cost as they do not require specialised saltwater conversion equipment.
✅ Effective Water Sanitisation – Chlorine efficiently kills bacteria and algae, ensuring clean, clear water when properly managed.
✅ Easier Repairs & Maintenance – Pool technicians are generally more familiar with traditional chlorine systems, making servicing simpler.
✅ Less Corrosive – Chlorine does not pose the same corrosion risk to metal objects and pool fittings as saltwater does.
Cons
❌ More Ongoing Maintenance – Chlorine levels need to be manually monitored and adjusted with frequent chemical additions.
❌ Potentially Harsh on Skin & Eyes – High chlorine concentrations can cause irritation, especially for sensitive individuals.
❌ Stronger Chemical Smell – Chlorine pools often have a noticeable chemical odour, particularly if not maintained properly.
Where to Buy in NZ
- Chlorine chemicals and accessories can be purchased from Bunnings and The Warehouse.
- Professional pool maintenance services and supplies are available through Poolwerx NZ.
Which Pool Type is Right for You?
Choosing between a saltwater and chlorine pool in New Zealand depends on your budget and how much time you’re willing to invest in maintenance. If you prefer a more hands-off, skin-friendly swimming experience, a saltwater pool might be worth the initial investment. However, if you want a cost-effective solution with easier repairs, chlorine remains a tried-and-true option.
Regardless of which type you choose, regular maintenance and using quality NZ-based suppliers will ensure your pool remains clean, safe, and enjoyable. Happy swimming!
