There's claims the Government needs to show its justification for intervening in Wellington City Council.

It's appointing a Crown observer - claiming it is financial mis-management for the Council to plan to fund water infrastructure from rates revenue - rather than debt, using a Government tool.

Lower Hutt Mayor Campbell Barry notes the Government only made its funding tool available in August, not June when the council decided its Long Term Plan.

Barry says this doesn't add up.

"What I think should hopefully clear up the matters is for the minister to release the advice that he received from officials - so we can all see and understand it in its full context."
