An anti-Three Waters group says reform is needed, but one size doesn't fit all.

It comes as Auckland, Christchurch and Waimakariri councils band together to launch a revised plan - keeping a water regulator, but ownership, control and accountability stays with councils.

Communities for Local Democracy had a similar plan, but was shut down by the Government earlier this year.

Chair of that group, Manawatu District Mayor Helen Worboys, told Kate Hawkesby their plan needs funding assistance, which they're happy to do.

She says they support assisting communities, but their overall message to the Government is don't micro-manage them.
