"Council is not in the position to finance a stadium through ratepayer funding and it is not on our current list of priorities.
"We are however open to considering a national stadium being funded from the private sector.
"I would welcome public debate around the design and location of any stadium which would provide council with valuable feedback on possible options for the future."
Goff had raised the prospect of a new stadium shortly after coming to office in 2016 and had received a pre-feasibility study from PwC, costing $932,000, recommending a run-off between five possible downtown sites and upgrading Eden Park.
He received criticism this year from councillors over his refusal to give them full and open access to the report.
Goff said earlier this year there was no money in the council's 2018-2028 budget for a stadium.
