Southern Cross Health Society is New Zealand’s largest health insurer — a member-owned not-for-profit covering around 900,000 New Zealanders. Its scale means strong negotiating power with hospitals and a large network of preferred providers. Here’s an honest assessment of its plans for 2026.
About Southern Cross
- Type: Member-owned not-for-profit society (not a shareholder company)
- Market share: ~60% of NZ private health insurance market
- Founded: 1961
- Claims history: Long track record; generally strong claims reputation
Being a not-for-profit means any surplus is reinvested into the society or used to hold premiums down — rather than paid to shareholders. In practice, Southern Cross premiums have still increased significantly over the past decade as healthcare costs have risen.
Plans Overview
Southern Cross offers three main plan types:
UltraCare
The flagship, comprehensive plan. Covers:
- Private hospital treatment (surgical and non-surgical)
- Specialist consultations
- Diagnostics (MRI, CT scans, blood tests)
- Cancer treatment (no limits)
- Physiotherapy and allied health (annual limits apply)
- Optical and dental (up to annual limits)
- Mental health inpatient treatment
Best for: Comprehensive cover with minimal gaps. Families and individuals who want the most thorough private health cover available in NZ.
Easy-claim
A more affordable plan focused on surgical cover and recovery. Covers:
- Private hospital surgical treatment
- Post-hospital physiotherapy and specialist follow-up
- Less optical, dental, and GP reimbursement than UltraCare
Best for: People who primarily want cover for major surgical events and are happy to use the public system for non-surgical care.
Wellbeing Plans
Modular add-ons for specific needs — dental, optical, GP visits, and allied health. Can be held standalone or alongside a hospital plan.
What Southern Cross Does Well
Preferred providers: Southern Cross has contracts with most major private hospitals in NZ (Mercy, Ascot, Waikato Private, etc.) — which typically means claims are handled directly between the hospital and Southern Cross. You don’t pay upfront and claim back.
Claims process: Southern Cross processes most claims promptly. The member app and online portal make routine claims relatively straightforward.
Cancer cover: No annual or lifetime dollar limit on cancer treatment — a meaningful advantage over some competitors.
Established network: Being the dominant insurer in NZ means most NZ health providers are familiar with Southern Cross processes.
What to Watch Out For
Pre-existing conditions: Like all NZ health insurers, Southern Cross excludes pre-existing conditions. They use a 3-year moratorium approach on some conditions — meaning conditions that don’t recur in the first 3 years of the policy may eventually be covered. Other conditions are permanently excluded.
Premium increases: Southern Cross premiums increase with age and annually at renewal. Over 20 years, premiums can become substantial — particularly for comprehensive UltraCare plans. Budget for this.
Excesses: You can choose your excess level (e.g. $0, $500, $1,500 per person per year). Higher excess reduces premiums — useful if you’re mainly concerned about catastrophic events rather than routine claims.
Waiting periods: Standard waiting periods apply — 2 months general, 6 months for mental health, 12 months for obstetrics.
