The company behind Ed Sheeran's New Zealand tour said security measures are reviewed every time an artist holds a show.
Brent Eccles, of Frontier Touring, said each time an artist held a show in New Zealand they provided a document with their security requirements, which varied for each performer.
The reassurances comes following the tragic explosions at an Ariana Grande concert in Manchester on Monday night.
The suspected terrorist attack killed at least 22 people and injured at least 59.
Eccles said artists would calculate the level of security they needed based on their own experience with their audiences.
Some artists might require concert-goers to go through pat-downs and wanding while others, such as Sheeran, might require a ban on back packs.
"We do everything we can based on everything we think might happen in New Zealand," Mr Eccles said.
He said Monday night's attack was "an awful thing".
"It makes everyone just shudder . . . it's a crazy world we're living in."
Ed Sheeran will be performing at three Auckland shows from March 24-26 next year, as well as two Dunedin shows on March 29 and 31.
Tickets for his Auckland shows went on sale today, and two of the shows appeared to sell out less than an hour after the tickets went on sale.
Last week's pre-sale demand saw the pop star add two extra Auckland shows and an extra Dunedin show to his original itinerary.
