An Eden Park group is urging Justice Minister Amy Adams to ban palm-sized alcohol sachets, which are being found scattered around the stadium grounds after big games.
An Auckland councillor representing the Eden Park Community Liaison Group is particularly worried that the sachets can be easily smuggled into events with booze restrictions, adding to the country's already high rate of alcohol harm.
Despite widespread concern that came with their entrance into the market in 2013 - and police dismay at the time - the sachets are still available at some bottle stores for less than $2 each.
Councillor Cathy Casey, a member of the liaison group, said Eden Park management was worried at how many were being taken into the grounds at big events, despite liquor licences banning people bringing their own alcohol.
In light of the complaints, she bought some of the 25ml sachets and was alarmed to find that Cheeky products, flavoured in three varieties and containing around 0.4 standard drinks each, carried a relatively high alcohol concentration of 20 per cent.
