What GSI Insurance Partners does

GSI Insurance Partners (legal entity GSI Insurance Brokers Auckland Ltd) is a New Zealand insurance brokerage founded in 2005 and headquartered in Auckland, with a second office serving the South Island. The firm operates as a non-aligned broker earning commissions from multiple insurance providers, complemented by advisory and claims advocacy fees, with no proprietary technology, SaaS platform or self-service software product; distribution runs through a team of brokers plus phone, email and website contact channels.

The company's offering is structured around three product lines: Professional Indemnity Insurance (including a specialized package for land surveying, civil engineering and multidisciplinary firms developed through its Diamond Partnership with Survey & Spatial New Zealand since 2013), Commercial Insurance (spanning material damage, business interruption, legal liability, cyber, commercial vehicles, financial risks, UAV/drone, marine and cargo, and residential property investment cover), and Domestic Insurance for high-value homes, contents and vehicles. Core distribution advantages include Lloyd's of London Coverholder status, Steadfast Group membership and a dedicated in-house claims team, with underwriting capacity drawn from major NZ and global insurers including AIG, Chubb, QBE, Zurich, Vero, NZI, Lumley and Ando.

GSI primarily serves land surveying, engineering and multidisciplinary professional firms (100+ clients), professional services businesses such as accountants, lawyers and architects, commercial property owners, and high-net-worth domestic clients, with operations concentrated in New Zealand and selected trans-Tasman servicing for clients such as ENGEO. Revenue is generated through broker commissions on placed business and professional services fees, with quote-based, annual-billing pricing tailored to client risk profiles. Leadership comprises CEO Matt Naylor (joined 2018) and Managing Director Glenn Stone, supported by two Associate Directors and a wider broker and claims operations team.

Core offering

GSI Insurance Partners is a tailored business insurance brokerage that sources, designs, and manages insurance policies for New Zealand businesses and professionals. It places cover with multiple insurers (including Lloyd's of London) across three core lines: Professional Indemnity (with specialty cover for surveying, engineering, and multidisciplinary firms), Commercial Insurance (material damage, business interruption, legal liability, cyber, commercial property, marine/cargo, vehicles, UAV, financial risks, residential investment), and Domestic Insurance for high-value homes, contents, and vehicles.

Product overview

GSI Insurance Partners operates as a tailored business insurance brokerage rather than a unified software platform. Its core offering comprises three main product lines — Professional Indemnity Insurance, Commercial Insurance, and Domestic Insurance — each encompassing multiple sub-products and specialized coverage packages. The Professional Indemnity line includes base PI cover plus industry-specific products for land surveyors, civil engineers, and multidisciplinary firms through the Survey & Spatial New Zealand partnership. The Commercial Insurance line spans material damage, business interruption, cyber, legal liability, business vehicles, financial risks, marine/cargo, drone (UAV), and residential property investment coverage. The Domestic Insurance line covers high-value home, contents, and vehicle risks. All products are sold and serviced through GSI's team of insurance brokers; there is no self-service software platform, API, or SaaS product. GSI differentiates through tailored policy design, a Cover-First approach, Lloyd's of London access, and a dedicated in-house claims team. Spart }an Finance provides related asset finance broking.
