However, yesterday's news only feels like the first chapter of the stadiums roundabaout and many more questions remain.
Where is the future home of speedway? What is the long-term strategy around Eden Park? What will happen to Albany Stadium? Will a downtown stadium come back on the agenda?
Answers will emerge, but it seems almost certain speedway will be moved from Western Springs. The RFA has agreed an extension on speedway's current lease until 2019, which gives both parties breathing space, but the council body sees cricket, AFL and baseball as the future of the Springs.
"We need to find speedway an appropriate long-term home," said Brooks, adding that the resource management constraints at the central Auckland venue were untenable.
Speedway spokesman Greg Mosen said he "didn't see any better alternatives" than staying at Western Springs but added that "we are realists, we know that life brings about change".
Colin Dale Park in Manukau is one of the prominent options at this stage, though Brooks said they were a long way from confirming anything.
Eden Park is a more vexed issue, as it is still massively underused and weighed down by huge debt. There are no major tournaments after the 2017 Rugby League World Cup and it's doubtful this country will host the Rugby or Cricket World Cups in the medium-term future.
The rationale behind the RFA pushing the Warriors to Eden Park was to boost its finances. Now that's off the table, what happens next, especially if Auckland loses the NRL Nines and international cricket matches are moved to Western Springs? Eden Park could become the white elephant critics of the Rugby World Cup redevelopment proposal always feared.
QBE Stadium will remain a hub for New Zealand Football - when the All Whites finally get back on the field - and is also home to North Harbour rugby, though their attendances have been poor for years. It is expected to host an All Blacks test in 2017.
But it seems inevitable that a central city rectangular stadium will come back on to the agenda, at least in terms of a discussion document, with both the Warriors and RFA open to exploring options in the long term.
But for now, the Warriors and their fan base can look forward at least another decade at Mt Smart.
The Penrose venue is far from the worst in the NRL - despite what detractors might claim - but does need some work.
Warriors chief executive Jim Doyle said the new agreement includes an undertaking to significantly upgrade the stadium and its facilities.
"This will include replacement seating, refurbishment of the dressing room facilities and a community classroom, while the agreement also allows for replacement floodlights, a new big screen and a facelift for various areas of the stadium," said Doyle.
