But he said that the cost of the project could not continue to keep rising.
"We do need to know if that is the full and final cost. We can't keep having these costs going up and up and up."
Christchurch City Council has received the largest amount of submissions on a public consultation topic in a decade regarding the future of the long-awaited stadium.
In just over three weeks, 29,200 submissions were received, with almost 4000 of those being on the last day.
The largest number of submissions before this project was its "Share an Idea" consultation after the 2011 earthquakes.
The projected price tag is now $683 million, with higher costs stemming from inflation, supply chain issues and workforce shortages.
Residents expressed whether to push ahead with an increased budget, pause the project and re-evaluate the design, or abandon the stadium altogether.
Mayoral candidate Phil Mauger told Checkpoint he had been told by the stadium board that the current price was fixed until July 15.
Councillors are set to make a decision on July 14.
Meates said if the cost of the project was final, he would agree to building the stadium.
"If it's a fixed price where it is a full and final cost and there are sufficient funds to enable the city to respond to other unplanned events, then yes."
Consultation for Te Kaha closed last night.
