They would do some things differently to avoid long queues at the bar and the toilets - "you can never have too many portaloos" - and would look at opening up the venue and parking areas earlier to spread arrivals over a longer period.
People who arrived at the start time faced delays getting in and long lines of traffic, worsened by an accident at Waipapa Landing.
Mrs Thompson said many people left home at 5.15pm for the 5.30pm start, which would not usually be a problem in Kerikeri. However, it meant thousands of concert-goers arrived at once. They will also consider arranging parking in town or the sports complex and providing shuttle buses to the venue.
Feedback from the sound and lighting crews was that the venue, with its natural amphitheatre surrounded by trees and vines, was one of the best they had seen.
Even the weather played ball with the sun putting in an appearance for the last hour of daylight. She was grateful to police and St John for helping make the night a success. The clean-up started at 7am yesterday and was complete by 10.30am.
Mrs Thompson hoped to secure another major international act next year, as a one-off show or part of a national tour. Work was under way to line up a band but it had not been finalised. The promoter who brought UB40 to Kerikeri liked to have her bands locked in by April or May.
Promoter Jackie Sanders said UB40 loved the Kainui Rd venue and its natural amphitheatre.
"They said it made it feel like the audience was right there with them," she said.
