Extend breast screening to 70-74
The Policy: National Breast Screening Policy — 2023 Election →
TL;DR
- Free breast cancer screening in New Zealand used to stop at age 69. This policy extends it to women aged 70 to 74, so they can keep getting free checks.
- The reason is that the risk of breast cancer actually goes up with age — a woman's risk is higher at 70 than at 50 — so stopping checks at 69 missed a group who still needed them.
- About 130,000 more women become eligible over each two-year screening round, which works out to roughly 54,000 extra screens a year once it's fully running.
- It's expected to catch about 60 more cancers a year, at an earlier and more treatable stage. Around 350 women aged 70 to 74 are diagnosed each year.
- The rollout is being staged from October 2024 (a pilot) through to full coverage by 2029, with new mammography machines, mobile units and extra staff being added to handle the demand.
- The policy also aims to close gaps for Māori and Pacific women, whose breast-cancer outcomes have been worse, partly through a new opt-out system that found about 135,000 women who weren't being screened.
More detail
Supporters point out that early detection works best alongside treatment: catching a tumour early is exactly when newer medicines (funded through a separate $604 million boost to the government's drug-buying agency, Pharmac) are most effective. So screening and medicines funding reinforce each other.
The open question is downstream. Finding more cancers means more women needing surgery and cancer care, and hospital waiting lists for planned surgery are already long. The full benefit of screening more women depends on hospitals and surgical teams having enough capacity to treat what the screening finds.
Full Detail if you want to know more
Pitched as saving lives by extending free breast screening to women aged 70–74 (previously 45–69).

Why it was proposed:
- Risk rises with age: a woman's risk of breast cancer is actually higher at 70 than at 50, yet free screening previously stopped at 69. Modelling for the Breast Cancer Foundation found older women who keep screening have a 42% lower risk of dying from breast cancer (Te Whatu Ora).
- An ageing population sharpens the case: the 65+ group grew to about 842,000 by 2020, passes 1 million by 2028, and reaches roughly 1.34–1.46 million by 2048 (Stats NZ).
- Equity: breast-cancer outcomes have been worse for Māori and Pacific women; the extension, paired with a new opt-out system (Te Puna) that surfaced about 135,000 under-screened women, aims to close coverage gaps as well as add years of eligibility.
By the numbers:
- About 130,000 more women become eligible (every two years), roughly 54,000 extra screens a year once fully rolled out.
- Around 350 women aged 70–74 are diagnosed each year; the extension is expected to catch about 60 more cancers a year at an earlier, more treatable stage.
- Context: NZ records about 3,878 breast-cancer registrations and 650+ deaths a year — among the highest incidence rates in the world (Breast Cancer Foundation NZ).
Does it join up with the rest of the system?
- Detection meets treatment: catching tumours at stage 1 or 2 is exactly when the new and widened therapies from the $604m Pharmac boost work best — so screening and the medicines funding reinforce each other.
- Screening capacity is being built for it: the four-year phasing is deliberate, and Health NZ is resourcing it with seven new mammography machines, ultrasound gear, four new mobile units and new fixed sites (Kāpiti Coast, Takapuna, Greenlane), plus radiographer and radiologist recruitment (RNZ).
- The remaining question is downstream: more detection adds to surgery and oncology demand while elective-surgery waitlists are already blown out and the Dunedin hospital rebuild was scaled back — so the screening build-out still needs hospital capacity to match.
The result (in progress):
Phased from October 2024 (pilot) to full coverage by 2029. Verdict: a deliberately staged, well-resourced and evidence-backed extension that reinforces the Pharmac investment and targets equity gaps — with its full payoff still hinging on downstream hospital and surgical capacity.

Key milestones
Age extension pilot begins (Nelson/Marlborough)
Free screening to 74 started as a pilot, to roll out nationally one year at a time.
Te Puna opt-out system finds 135,000 under-screened
A new digital invitation system shifted screening to opt-out and identified ~135,000 eligible women not being screened.
National rollout begins, phased to 2029
The extension began rolling out nationally, one birth-year each October, complete by October 2029.
Why: risk is higher at 70, and screening cuts deaths
Breast-cancer risk rises with age; modelling found older women who keep screening have a 42% lower risk of dying from it.
Impact: ~54,000 more screens, ~60 more cancers caught earlier
Once fully rolled out, about 130,000 more women are eligible and ~60 more cancers a year are expected to be found at an earlier stage.
An ageing population grows the need
The 65+ population passes 1 million by 2028 and ~1.4m by 2048, steadily enlarging the eligible group.
Capacity scaled up for the rollout
Seven new mammography machines, ultrasound gear, four mobile units and new fixed sites (Kāpiti, Takapuna, Greenlane), plus workforce recruitment.
Free screening opens to thousands more women
The national age extension began, opening biennial free screening to many more 70–74 year-olds.
