The Otago Regional Council is taking aim at its district counterpart, by opposing a draft plan for the wider city area.
The ORC has prepared two submissions on the Dunedin City Council's second generation district plan.
As a landowner, the ORC says the plan doesn't represent sound resource management practice.
It says the plan won't promote efficient use or development of local resources, and is contrary to parts of the relevant government legislation.
The ORC's submission as an authority includes almost 50 separate requests for changes.
But it also highlights the ORC's support for other sections of the plan.
The DCC has received over 1000 submissions on its draft plan.
