"Because they've been stuck in Auckland, they haven't been able to do any site visits. But we've sent them a whole lot of photos and we're only just starting that process."
Murphy said he began speaking with the Six60 promoter about an event more than two years ago.
"We've been working on getting a concert for the last three years or more, so it's really been something we've been wanting to target for a long time."
The venue has a maximum occupancy of 25,000.
Hawke's Bay Today understands the stage will be at the grass end so the band will be playing into the stadium, though details have yet to be confirmed.
Turf protection would be provided by the promoter.
It would be a change from the stadium's regular mix of rugby, cricket and other sporting events, Murphy said earlier.
