The number of Māori aged 65+ will more than double (from 48,500 to 109,400) between 2018 and 2034, as will the senior Pacific population (from 21,300 to 46,700), while the number of senior Asian New Zealanders will almost triple (from 59,500 to 171,900).
Seniors currently make up around 6.2 per cent of the workforce, but that is expected to grow to 10.6 per cent by 2033.
The demographic shifts will have implications for the economy, workforce, housing, health and aged care, and social services, Martin said.
Better Later Life has five key areas for action:
• Financial security and economic participation
• Healthy ageing and improving access to services
• Diverse housing choices and options
• Opportunities for participation and social connection
• Making environments accessible.
"For example, two key areas of the strategy are supporting seniors in the workforce, and promoting housing options appropriate for older people," Martin said.
"It is also important as a country that we have policies and initiatives that help people to keep connections throughout their lives and stop them being isolated or lonely.
"Ageism, discrimination, negative stereotypes and attitudes towards older people all impact on the quality of later working lives and are considered in the strategy."
An action plan will be developed based on the strategy's key areas and progress will be tracked by two-yearly reporting on what has been done.
The Government has already upgraded the SuperGold website and announced plans to introduce a new SuperGold app.
It also has the Age-friendly New Zealand programme which, among other things, aims to have wide pedestrian crossings and footpaths, public transport to health centres, shops and parks, and affordable housing close to services.
Martin launched the strategy at the Better Later Working Lives Forum at Parliament this morning.
"The forum is a great opportunity to talk about the ageing workforce and to address the challenges that people over 50 often face in participating in the workforce."
