Why New Zealand tax professionals choose Nylon over Lexis+ with Protégé
Lexis+ with Protégé is strong for broad legal research, with CaseBase and The Laws of New Zealand. Nylon is built for cited tax answers from the primary sources, wherever you work.
Research inside your AI assistant
Adviser and Elite seats bring Nylon into Claude, ChatGPT and Microsoft Copilot, with every answer cited. LexisNexis’s public pages don’t describe a connector for Claude or ChatGPT.
Built on tax law
Nylon answers from New Zealand legislation, Inland Revenue guidance, and court and tribunal decisions, and links each citation to the source. LexisNexis writes its New Zealand pages for legal professionals. Neither its New Zealand content library nor Practical Guidance lists a tax practice area, and Inland Revenue guidance isn’t described on its public pages.
No minimum term
Nylon is billed monthly and you can cancel anytime. LexisNexis’s New Zealand terms say you can’t cancel during the minimum term in your order, and the subscription then renews for 12 months at a time.
Per-user prices, published
Nylon publishes a per-user price for Starter, Adviser and Elite. Lexis+ with Protégé is quote-only: LexisNexis tailors the price to your team size, the capabilities you need and your content access.
