Question 1

Does NZ health insurance cover pre-existing conditions?

Accepted Answer

Two models exist across NZ insurers. Southern Cross uses disclose-and-accept (you tell them every condition at application; they accept or decline per condition). nib uses stand-down (no cover for pre-existing for typically 3 years, sometimes with permanent carve-outs for specific conditions). The verbatim rule for every product is on each insurer-review page.

Question 2

Are non-Pharmac cancer drugs like Keytruda covered?

Accepted Answer

Not by default. Most NZ health policies cover Pharmac-funded chemotherapy in the standard hospital benefit. Non-Pharmac high-cost cancer drugs (Keytruda, Opdivo) need a specific non-Pharmac drug benefit — Southern Cross UltraCare and certain nib + AIA tiers include this as an upgrade. The exact annual sublimit varies by plan and is set out verbatim on each insurer review page.

Question 3

Does NZ health insurance cover IVF and assisted reproduction?

Accepted Answer

No — IVF, assisted reproduction, fertility treatment and surrogacy are universally excluded under every NZ retail health insurance product. The narrow exceptions (limited diagnostic testing, certain hormone treatments) vary by plan and are spelled out on the fertility cover page.

Question 4

What mental health treatment does NZ health insurance cover?

Accepted Answer

Entry-level / hospital-only plans usually exclude mental health entirely. Mid-tier and comprehensive plans cover psychiatric hospitalisation with an annual sublimit set out in the wording. ADHD assessment, eating disorders, and developmental conditions are commonly excluded — see the mental health page for each insurer's verbatim rule + sublimit.

Question 5

Does maternity cover include routine pregnancy and birth?

Accepted Answer

No — routine maternity and birth run through the public LMC (Lead Maternity Carer) system and are publicly funded in NZ. Private health insurance covers high-risk pregnancy complications, surgical interventions, and post-natal allowances on certain plans. Sublimits and exclusions vary materially.

Question 6

How does ACC interact with NZ health insurance?

Accepted Answer

ACC covers accidents — so most NZ health policies exclude ACC-eligible events from their hospital cover. The catch: ACC sometimes declines coverage on edge cases (chronic gradual-onset conditions, pre-existing flares triggered by minor accidents), leaving you with neither. See each insurer's ACC interaction rule on their review page.
