Cyclone Gabrielle

Once again, our thoughts are with our members, other colleagues and residents battling against flood waters and storm damage. It’s been a very tough start to 2023 and it's particularly difficult to see such devastation so close to home. These weather events also highlight the need for more focus on stormwater and floodwater management as an increase in the frequency and intensity of major storms is inevitable. Kia kaha.

Supporting the water and wastewater industry in NZ for 90 years

LGOIMA amendment provides for better hazard information

In our submission on the Local Government Official Information and Meetings Amendment Bill, Water New Zealand supported the objectives of the amendments:

  • ensuring that LIMs provide natural hazard information to property buyers that is clear, concise, nationally consistent in its presentation, and easily understood.
  • providing certainty for local authorities about sharing natural hazard information in LIMs and reducing exposure to legal liability.

The LGOIMA amendments, supported by wider Government initiatives, will enable clear, concise, nationally consistent hazard information to be included on LIMs.

Bemused by the political furore, nay fury, Newsroom's Nikki Mandow went hunting for examples of shared governance in action.

“If you want to break down Three Waters, it’s pretty simple. We want to be able to drink the water, we want to make sure the storm water is going out, and so on. And like what we are doing with Kotahitanga mō te Taiao Alliance, it’s about thinking big, not getting into silos – this little council, this little iwi, says Alliance co-chair David Johnston.
