About International Specialty Aggregates (ISA)

International Specialty Aggregates (ISA) has been established in the pebble export industry in New Zealand since 2002. ISA quarries, screens, packages and distributes its own various colours and grades of pebble along with construction aggregates. Our pebbles are 100% natural and are sourced from our quarries located in the South Island of New Zealand.

The products are used principally for stone lining of swimming pools as well as a key component for manufactured decorative products and decorative landscaping.
