A Six60 fan was left disgusted after concertgoers left behind a "sea of waste" at Western Springs.
Laura Tynan from Hamilton captured footage of the "gross" aftermath that spread across the ground of the Six60 concert on Saturday, February 3.
In the video, concertgoers can be seen leaving the venue, crumpling and kicking plastic cups on their way out.
"Heaps of people didn't even care," Tynan told the Herald.
"It was the first time I've been to a concert at Western Springs so I wasn't sure if it was always like that.
"I did notice that there were only about six rubbish bins on the whole field area, which filled up almost before the first set played.
"Everyone around us was dropping their rubbish because there was nowhere else for it to go.
"They definitely should have had more bins. I thought it was disgusting."
The Herald has contacted the promoters of the Six60 event for comment.
This is not the first time excessive waste being left behind at a concert has been mentioned.
A Wellington man was shocked by the "sea of plastic" left behind after Eminem's concert at Westpac Stadium on Saturday.
Peter Steele was at the concert with friends and took a photo of the mess left behind by the 46,000 attendees.
"I just saw a sea of plastic, it looked like it had hailed," he said.
"The conversation just started with 'what a mess, what pigs, where do they go, that's appalling'."
Steele said so much fuss was being made over plastic bags at supermarkets when massive amounts of plastic cups were being used at such events. He believed there would have been at least 100,000 cups.
He and his friends discussed music festival Coastella, and how attendees had been able to purchase a $3 cup which they used throughout the festival and were able to return for a refund at the end.
Anyone who didn't want to wait in line for their refund could put the cups in a bin, and charities could collect the refunds for their cups.
Steele questioned whether such a measure could be taken at Westpac Stadium.
A stadium spokeswoman said the amount of rubbish collected by the post-event cleaning crew was standard for a concert of this size.
"All rubbish was cleared on the night of the concert. All waste is collected and sorted by our post-event clean-up crew and plastic and other recyclable products are sent for recycling locally."
Organisers have already put in place processes to reduce waste, and are looking for other alternative sustainable solutions.
Changes include serving all food in non-plastic, recyclable containers, recycling all bottles and cans after pouring beers, RTDs and wine, and recycling all cardboard packaging.
There are no straws provided in the venue and the stadium no longer provides plastic lids with beers.
"We are also looking at reusable and compostable cup options," she said.
Eminem's 2019 RAPTURE tour set the record for the fastest ever sell-out concert at Westpac Stadium and drew in 46,474 attendees.
