Why Are We The Best?

To be a respected and sustainable insurance broking and consulting business.
To develop a profitable business based on the retention of existing clients and the addition of new clients. Superior customer service backed by industry experience and knowledge will underpin our value proposition to clients.
TSI was established by Trevor and Cheryl Strong on Auckland’s North Shore. The business continues to grow and now has locations in Auckland, Tauranga, Coromandel, Gisborne and Masterton, providing insurance broking and consulting services across NZ and overseas.

We have a long history supporting clients in these industries throughout New Zealand. Our knowledgeable team are experts in these fields and help businesses to identify their exposures and risks, then aim to either eliminate, reduce or insure that risk.

Arranging and maintaining the appropriate insurance coverage, supported by managing claims when they occur is the TSI point of difference. With our combined broking, underwriting and claims handling experience our team are meticulous about selecting the right insurer and insurance coverage to suit the individual needs of our clients, and importantly manage the claims process.
