HERE’S HOW IT WORKS
You’ll get 6 weeks free in your first year (as a cashback refund) if you maintain continuous membership until 23 January 2023.
Then simply activate and engage with AIA Vitality, our science-backed health and wellbeing program, and maintain AIA Vitality Silver Status or above and you’ll get a further:
3 weeks refunded in January 2024, and
3 weeks refunded in January 2025.
Access to the Vitality program is a fun gimmick to incentivise getting healthier, but I've done a comparison on my end and even with the monetary incentives, 12 weeks free cover and other savings (e.g. 50% off gym membership), its still more expensive than my current health insurer with less benefits (extras, hospital cover).
Also be warned that as OP mentioned, 12 weeks is only actualised if you stay with them for 3 years, whether you want to stay with them for that long should probably factor into your decision.
