Rotorua Lakes councillor Janet Wepa said the bylaw review was part of a review of the waste management strategy.
"We used to get about 60,000 tonnes of waste but over the past five years this has declined. We think that may be because we are recycling and there are more people minimising waste, which is a good thing.
"The council's income has gone down."
She said the council would have made a decision on the bylaw by mid-2016.
"We will be looking at what the bylaw covers [which] is what we accept and what we don't accept in the landfill.
"We have got space in our landfill for 50 to 100 years so we do have to think about how to manage it without costing the ratepayer too much."
Mrs Wepa said there could be ongoing issues involved in accepting rubbish from other cities, such as the potential for the Government to impose fines on emissions.
"If we open it up to other places to bring their rubbish - and that's one part of what we have to think about - because one of the issues being that rubbish makes emissions ... in times to come we could see fines of up to $15 million.
"We are trying to find ways to keep our landfill there but manage it in a way that has less impact on the environment and less costs on the ratepayer."
Keep Rotorua Beautiful chairman Craig Morley was not in favour of the idea to bring in rubbish from other districts, but said the council needed to find ways to keep the landfill running.
"As far as funding costs they are trying to secure, I don't think importing someone else's rubbish is the answer from an environmental point of view and from a sustainability point of view. However they do need to try to keep the landfill open."
