Dunedin Venues Management Limited (DVML) has revealed the Eagles concert on March 2 and the Six60 show seven days later brought in $16million to the local economy.
Of the 50,000 people who attended the two shows 27,453 were from out of town.
Fleetwood Mac will be returning to Dunedin on September 21 after previously injecting $10.1million into the region after performing at the stadium in November 2015.
Forsyth Barr hosted eight concerts last year and DVML chief executive Terry Davies is optimistic about the future.
"The support from the region through high tickets sales has been outstanding and gives very positive signals to promoters for future concerts. With two concerts already on the calendar for February next year and Fleetwood Mac still to come this year, we are feeling very positive."
Earlier this year, Elton John announced his farewell tour would include another concert at the stadium on February 4, 2020 and Queen and Adam Lambert perform on February 10.
