Investing In Older Adult Vaccination: A $1 Billion Opportunity For New Zealand's Health And Economy
Press Release – GSK New Zealand
In addition to preventing over 8,000 hospitalisations, 137,000 GP visits, and over 2,400 emergency department presentations, the vaccination programme would also increase productivity and volunteer contributions from older adults.
A new report released today highlights the significant return on investment (ROI) New Zealand could see from a comprehensive older adult vaccination programme.*
The report – Prevention Pays: The Economic Value of Adult Vaccination – underscores how a nationwide publicly funded vaccination programme for influenza, shingles, and respiratory syncytial virus (RSV) for those aged 65 and over can significantly reduce pressure on the New Zealand health system while generating substantial economic benefits.
The report, commissioned by GSK and independently conducted by Evaluate Consulting, an economic consultancy specialising in cost-benefit analyses and social policy, shows that investing in adult vaccination would result in an return on investment (ROI) of $1.93 – $2.17 for every dollar spent, providing a total economic benefit of over $1 billion over four years.
In addition to preventing over 8,000 hospitalisations, 137,000 GP visits, and over 2,400 emergency department presentations, the vaccination programme would also increase productivity and volunteer contributions from older adults.
Key highlights from the report include:
• A return on investment (ROI) of $1.93–$2.17 for every dollar invested in the vaccination programme. • Over 8,000 hospitalisations and 137,000 GP visits could be prevented over four years.
• 4.8 million additional carer hours and 3.9 million additional volunteer hours, over four years, as a result of older New Zealanders staying healthy
• A total net benefit of over $1 billion at 60% vaccine uptake (similar to the current influenza vaccination) when factoring in healthcare savings, productivity, and caregiver contributions.
Hon Steven Joyce, Former Finance Minister and Director of Joyce Advisory Ltd commented on the report, saying: ' As our population ages, the need for innovative approaches to healthcare has never been more urgent. The findings in this report offer a clear pathway to improving the health of older New Zealanders and strengthening the broader economy, all while reducing the stress on the health system. The return on investment for this sort of public vaccination programme is undeniable, providing nearly double the value for every dollar spent, even when measured on a very conservative basis.'
Chair of General Practitioners Aotearoa (GPA), Buzz Burrell added: 'Vaccination is one of the most cost effective health interventions available. By preventing common illnesses, we reduce the strain on our overstretched health system, free up critical resources, and, most importantly, improve the lives of older New Zealanders. This report makes a compelling case for increased investment in adult vaccination.'
The findings of the Value of Adult Vaccination report come at a time when demand on New Zealand's healthcare system is growing due to an aging population. The report shows that preventative healthcare, like an older adult vaccination programme, offers one of the most cost-effective ways to reduce hospital pressure, improve quality of life for older New Zealanders, and boost the economy through increased productivity, including volunteer and carer contributions.
Older adults are a key economic force in New Zealand: around 25% of adults over the age 65 are in paid employment, ** around 1 in 8 are an informal carer3, and nearly 60% of adults aged 65-75 undertake volunteer work.****It is estimated that in 2022 the economic contribution of caring was $17.6bn or 5.4% of GDP. ***
Amanda Southcombe, General Manager, GSK New Zealand said: ' We are committed to improving the health of communities around the world. This report highlights the clear economic and social benefits of investing in adult vaccinations for older New Zealanders. By focusing on prevention, we can ensure that individuals remain healthy, stay active, and contribute to society, while reducing the long-term burden on our healthcare system and deliver significant returns for everyone,' she said.

NZNO Backs People's Pay Equity Select Committee
Press Release – NZNO NZNO Primary Health Care Nurses College chair Tracey Morgan says it was devastating to the 5000 primary health care members that their claim was scuppered without warning or legitimate reason. Representing a third of the pay equity claims scrapped by the Coalition Government, NZNO is throwing its full support behind the People's Select Committee on Pay Equity. Members of the New Zealand Nurses Organisation Tōpūtanga Tapuhi Kaitiaki o Aotearoa (NZNO) had 12 pay equity claims being progressed across the health sector including aged care, primary health care, hospices, Plunket, community health and laboratories when the scheme was gutted on 6 May. These claims covered almost 10,000 nurses, health care assistants, allied health workers and administration staff. A further 35,000 NZNO Te Whatu Ora members had their pay equity review halted by the changes, meaning their pay would again fall behind. NZNO Primary Health Care Nurses College chair Tracey Morgan says it was devastating to the 5000 primary health care members that their claim was scuppered without warning or legitimate reason. 'It was antidemocratic and an attack on women for the Government not to have consulted the workers whose lives they were changing. Primary and community health care nurses, like their hospice, Plunket and aged care counterparts, accepted lower wage increases in their collective agreements on the understanding they were likely to receive pay equity settlements. 'Now they can have their say through the People's Select Committee on Pay Equity. 'The committee of 10 former women MPs from across the political spectrum are strong wahine who helped establishment the previous system to address the gender discrimination which has kept down their wages their whole working lives.' Most New Zealanders – 68 percent – believe the Government should have consulted on the changes, a new poll released today found. Tracey Morgan says NZNO urges all its members to submit their views to the Select Committee so they can be heard when it meets in August.
