O-I New Zealand (formerly known as ACI Glass Packaging), based in Penrose, Auckland, is the only manufacturer of glass bottles and jars in New Zealand.

Since its establishment in 1922 it has gone from producing 50,000 bottles per week to 50,000 bottles an hour, catering for a variety of beverage and food customers throughout NZ. It operates two glass furnaces from its Auckland plant. These furnaces run continuously and are re-built every 12-15 years. At the same time, new technological advances are included.
