More events across the board could be coming to Auckland's Eden Park.

RMA Minister Chris Bishop will lead an investigation into local rules impacting the number of concerts and sporting events that can be held and curfews impacting how long they can run for.  

Currently, only 12 music events and 25 night-time sports fixtures can be held each year, while conferences can't have more than 2000 people.  

Tourism Minister Louise Upston says Eden Park should have the flexibility to host any large-scale event that boosts the economy.

"Whether it's an add on to a convention that we're hosting at the NZICC for 3,000 people and they want to do a dinner offsite and Eden Park makes sense - we want to be able to just get on."
