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

Shark Teeth™ is proudly designed and built in Hawke’s Bay, New Zealand by parent company McLaren Smart Processing. With over a century
of innovation and craftsmanship behind its name, McLaren’s began as a modest operation rooted in the Kiwi values of hard work and genuine care. Over the decades, the company has grown to achieve a global reputation, particularly recognised for its automated food processing machinery.

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

Shark Teeth™ deliver practical, dependable solutions that stand the test of time—exemplifying the very best of New Zealand manufacturing.


“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.”
