"We have come to an agreement with Mr Buckley that buys some time for Auckland Council to organise a permanent home for Speedway," Barnes said.
"We have succeeded in resolving the matter for now so Speedway can continue uninterrupted in the short term, but some critical and urgent decisions have to be made by Auckland Council so we do not find ourselves in this situation ever again."
The agreement is aligned with an earlier, expired memorandum of understanding which had allowed SPL to continue its events at Western Springs until the end of the 2019-2020 season, while efforts were made to secure a suitable alternative venue for the speedway classes operating at Western Springs.
Barnes said RFA considered it reasonable to renew the offer of a one-year extension while the other deliberations around an alternative venue continued.
Buckley said: "Speedway's view is that the proposed alternative venue of Colin Dale Park would be suitable, but we cannot move from Western Springs until it is ready, and council has not yet approved the necessary funding to upgrade it.
"Speedway has a lot of very passionate supporters and we were never going to be thrown out of our home without an alternative in place.
"We appreciate RFA's collaborative approach in finding a short-term solution, but the problem remains and only council can solve it. RFA and I have agreed that unless council fixes this we will all find ourselves back dealing with this in a year's time."
Barnes said the RFA would work "collaboratively" with Auckland Council, something he said they had done with Buckley.
"But it is council's responsibility to take the lead and find a permanent home which meets the needs of Speedway fans and is appropriate for Auckland's ratepayers.
"Speedway is part of the city's sporting culture and it is not acceptable for it to have nowhere to go."
Goff welcomed the agreement between Regional Facilities Auckland and Springs Promotions Ltd to extend Speedway's lease at Western Springs.
"I asked everyone to take a step back and think realistically about the most sensible option for Speedway and today we have made some progress.
"An extension for one season at Western Springs provides surety for Speedway and its fans for next season and allows all parties time to agree on a new permanent home for Speedway in Auckland."
He supported Buckley's vision to move speedway to Colin Dale Park which will allow the sport to grow without the constraints currently imposed by the Environment Court on the number of meetings that can be held.
"Colin Dale Park future-proofs speedway.
"It can hold events at Colin Dale Park without limitation and without opposition from neighbouring residents concerned about noise or disturbance to their lives.
"It also allows a fit for purpose, safe track to be built there."
