At this month's meeting of the council's property and community services committee Whanganui mayor Hamish McDouall said a region-wide approach made sense.
"We've only got a limited amount of pie in the region," he said.
"We should acknowledge that we all can't have a velodrome, we can't all have a Manfeild or a rugby venue that can host test matches."
McDouall said it had Whanganui has some of the best facilities in the region.
"We've got the number one athletics venue in the region, Cooks Gardens is an internationally recognised facility."
The study's summary report said "historical decision making in respect of new or replacement facilities has often been undertaken on ad-hoc basis".
It said population growth and the need to replacement facilities will put demand of funding so there was a need for the whole region to work together.
Gosney said the study was being presented to councils as a major asset owner alongside the Ministry of Education and the idea was the study would guide future decisions.
