The Department of Conservation (DoC) says it no longer opposes the proposed expansion of Dunedin's main port.
Resource consents are being sought for the Port Otago project which could see the channel dredged to a maximum depth of 15 metres over 20 years.
DoC Otago conservator Marian van der Goes says the department was initially opposed to the proposal because it believed there needed to be tighter conditions on the project.
Ms van der Goes says Port Otago has agreed to a greater degree of monitoring than proposed in its resource consent application.
She says the monitoring information will be made available to a group of which DoC will be a part.
A resource consents hearing into the proposed expansion is underway in Dunedin.
