The size and type of the rainwater collection system that you can install will depend on your individual property and what you want to use the water for.
The easiest system to install is a rainwater barrel. These can be used for watering the garden and don’t require a pump or treatment system. Rainwater is great for your garden because soil doesn’t require water to be treated first.
What to consider:
Check out Eco Matters detailed guide to building your own rain harvesting kit.
As well as the big DIY stores there are smaller operators that sell rainwater harvesting barrels.

Contact your Council’s building consent team to find out more. Hamilton City Council has a practice note that outlines the requirements for rainwater tanks for on-site stormwater management, you can view it here.
