Simpson Grierson

What Simpson Grierson does

Simpson Grierson is one of New Zealand's leading full-service commercial law firms, headquartered in Wellington with a second office in Auckland and a staff of 251–500. The firm was founded in 1887 and serves three primary customer segments: commercial enterprises (banking, corporate M&A, property developers, energy companies, agribusiness); government and public sector (central agencies, local authorities, council-controlled organisations and major public infrastructure programmes); and a niche sports, entertainment and venues practice (national sports organisations, media and venue operators). Service delivery spans 14 practice areas — including Banking & Finance, Corporate & M&A, Competition, Construction, Employment, Environment & Planning, IP, Litigation, Public Law, Real Estate, Tax and Technology — and 11 focus industries, with recognised specialist depth in water and wastewater, urban development, infrastructure, local government, and sports law.

The firm's underlying 'technology stack' is professional services expertise rather than software. It operates a quote-based, per-matter fee model with multi-year contract cadence; fees are not publicly disclosed. Client acquisition is driven by direct partner relationships, professional referrals, government procurement, and a thought leadership programme (white papers such as 'Taking the Pulse of Local Government' with LGNZ and 'Connecting Canterbury' with Infrastructure New Zealand). In June 2026 the firm selected Legora as its legal AI platform to support research and document analysis, and it operates a Digital & New Technologies Including AI practice advising clients on emerging-tech regulation. Simpson Grierson operates exclusively within New Zealand and is privately held under a traditional partnership structure with no disclosed parent company, funding rounds or institutional investors.
