Our customers have been putting Shark Teeth™ anti-exit barriers through their paces for nearly 30 years.

McLaren Smart Processing in New Zealand invented Shark Teeth™ back in the mid-90’s to help a busy local supermarket cut down on theft and improve their customer flow into the store.

Word travels fast in the supermarket business, and today you’ll find Shark Teeth™ in high customer traffic environments throughout New Zealand and Australia.


“We get around 60,000 customers through our store every week. The entry takes a hammering and Shark Teeth have proven their worth over and over again.”
