At 11.59pm on Sunday the country moved back to the red traffic light setting in an effort to slow down the virus and it appears that people have listened to the Ministry of Health's advice to have pain relief on hand.
Pictures show just a handful of pain relief stock left at Countdown in New Lynn and at a Chemist Warehouse.
In the event of testing positive for Omicron and having to stay home, the Ministry of Health advised having pain relief such as ibuprofen and Panadol to hand, as well as a kit with hand sanitiser, masks, tissues and cleaning equipment such as gloves, rubbish bags and cleaning products.
Although customers may see gaps on the shelves they reassured shoppers that there are enough essentials for everyone to shop normally.
"We also saw shoppers pick up their usual pantry staples liked tinned goods, rice and pasta as well as everyday household items like toilet paper and pain killers," Wooster said.
