Provider Profiles
Southern Cross Health Society
BEST VALUE PREMIUMSNew Zealand's largest health insurer with over 900,000 members — and the most affordable comprehensive cover in the market. Southern Cross is a not-for-profit society (established 1964), which means profits stay within the business to benefit members. Its 2026 premiums are consistently 20–35% below nib and Partners Life for equivalent cover. The Wellbeing plan range suits most New Zealanders, from entry-level surgical cover through to UltraCare comprehensive.

Accuro — now underwritten by UniMed
HIGHLY RATED ⭐Accuro merged into UniMed (completed May 2024), forming New Zealand's third-largest health insurer with 140,000 members. Both brands continue operating — Accuro policyholders deal with the Accuro team; UniMed policyholders with UniMed. Both are now underwritten by the same not-for-profit mutual society.
Accuro's SmartCare plans offer the second-lowest premiums in the market, and crucially, it remains the only NZ insurer offering mental health cover as a specific optional add-on — making it the best choice for anyone prioritising mental health access. All other providers bundle limited mental health benefits within their major medical plans.

Partners Life
BROADEST WORDINGSPartners Life is known across the NZ insurance industry for having the most comprehensive and clearly defined policy wordings — fewer grey areas means fewer disputes at claim time. Acquired by Dai-ichi Life Insurance (Japan) in 2023. Premiums are among the highest in the market, particularly for female policyholders, but the policy definitions and comprehensive trauma/income protection range make them a strong choice for those prioritising breadth of cover over cost.
