Quick answer

Yes. Watercare adds chlorine during treatment and monitors residual chlorine across Auckland’s network. Auckland water is generally considered soft, so chlorine and hardness are separate questions.

What is in Auckland tap water?

Watercare states that chlorine is added during treatment to kill harmful micro-organisms that may remain after filtration. It also monitors residual chlorine as water moves through the Auckland network.

Watercare describes Auckland water as comparatively soft because its metropolitan plants mainly use surface-water sources that are relatively low in calcium and salts.

What this means in the shower

A warm shower can make a disinfectant smell easier to notice. If chlorine is the thing you want to address, compare the filter medium and published chlorine test rather than relying on a long list of stages.

A shower filter treats water only at that shower outlet. It may reduce selected substances according to its media and test conditions, but it does not make hard water soft or replace official drinking-water advice.

Watercare describes Auckland’s metropolitan supply as generally soft. A shower filter is not a water softener and will not remove hardness minerals.
