Residents have been complaining about the smell for more than a decade and councillors have now agreed to shift processing to an industrial site in South Hornby.
Ecogas would run the plant, processing the city's green waste from late 2026.
In the meantime, a short-term solution was for the first processing stage to be done indoors in Bromley, and the second at the Kate Valley landfill in North Canterbury.
Council said this could be implemented by April next year.
But Bromley resident Vickie Walker says this still means another summer with the stench.
"Nothing changes until April next year. Long-term, it sounds positive that it's going to close and move, but it won't open in the next place until 2026.
"For them to say they're going to process this inside the Bromley plant in the meantime and not have a smell ... I just feel that, why couldn't that have happened before now? If they knew that's what they needed to do, why didn't they do that before now?"
Walker wrote a letter to the council saying the odour was ruining her quality of life and believed the only option was to shut the plant now.
"God help them if they have a problem over there at the new plant - because what we've been through, I'd never want anyone else to go through it," she said.
The council said there would not be any smell from the South Hornby plant because it would be fully enclosed.
Kerbside organics and garden waste would be converted into products such as fertiliser, biogas and biofuel, and the new plant was expected to reduce emissions by 80 percent compared with the current one's operation, it said.
Hornby ward councillor Mark Peters said the council had worked as quickly as it could to find a solution.
"It feels like a long time, and far too long for the residents of Bromley to have suffered like they have. But, things do turn slowly in council circles and staff have had a real focus on finding a solution and getting it in place as soon as we can.
"We're committed as a council that should there be any ongoing problems [in Bromley], we will look with urgency to try and get on top of it."
Mayor Phil Mauger said the outcome was a win for the city.
"The location of the long-term solution has been carefully considered. The new plant will be located in an industrial area, which is zoned for this type of activity.
"The plant will deliver a totally different system from how we do things at the existing Organics Processing Plant at Metro Place in Bromley."
The Ōtautahi Christchurch Regional Organics Processing Facility will be located in Aruhe Rd in South Hornby.
The Bromley suburb has also been plagued by a putrid stench from the wastewater treatment plant after it was badly damaged by fire in 2021.
