Surviving Dry Periods in New Zealand: Think Rainwater Harvesting

Surviving a dry spell in New Zealand, or any other region, can be challenging, but rainwater harvesting is an effective and sustainable way to manage water resources. New Zealand, despite its reputation for lush landscapes, does experience droughts and water shortages in some areas, making rainwater harvesting a valuable practice. Here’s how you can think about rainwater harvesting to survive dry periods in New Zealand:

Understanding Rainwater Harvesting 

Rainwater harvesting is an important and sustainable practice in New Zealand, particularly in regions where water resources can be limited during dry periods. Here’s an overview of rainwater harvesting in New Zealand:

Benefits of Rainwater Harvesting 

Water Security

During dry spells, you’ll have a reliable source of water for essential household tasks such as flushing toilets, watering plants, and even drinking (with proper treatment). 

Cost Savings

Utilizing rainwater can significantly reduce your reliance on expensive mains water, leading to lower water bills. 

Environmental Impact

Rainwater harvesting reduces the demand for local water sources and minimizes runoff, helping to preserve the environment. 

Drought Resilience

By harvesting rainwater, you’re actively contributing to drought resilience in your community and conserving precious water resources. 


Embracing rainwater harvesting aligns with New Zealand’s commitment to sustainable living and responsible water usage. 

Legal Considerations

Rainwater harvesting is generally encouraged in New Zealand, but there may be local regulations and guidelines to follow. Regulations can vary between regions, so it’s essential to check with your local council or authority for specific requirements.


It’s wise to have a backup water supply or access to alternative sources during extended dry spells when rainwater alone may not be sufficient. Rainwater harvesting is a practical and environmentally responsible way to supplement your water supply in New Zealand, contributing to water conservation efforts and helping to manage water resources effectively in regions prone to droughts and water scarcity.
