Hi all,
I'm a 40 year old nurse who is holding out for the backpay from the government and am currently making an investment plan for when it arrives for retirement.

Background:
Mortgage of $350,000 over 25 years (due to pay off a lot earlier)
Kiwisaver - $26,000 ( due to withdrawing to buy first home 4 years ago).
Otherwise debtfree, no other real savings due to paying down debt as fast as we could.
(Partner has no plan for his retirement other than kiwisaver and he is nervous of investing)

Goal:
Financial freedom in 50s and beyond (mortgage free ideally and a nice cushion to see me through retirement comfortably)

Plan:
Investing.
Invest the majority of my backpay and regular deposits of $500/month and extra money throigh overtime etc.
This is where I keep overthinking. I was recommended a growth fund with Simplicity to essentially set and forget. Then I think about picking funds through Sharesies or similar (and decide against with their new fee structure).
I'm so overwhelmed with NZ podcasts, books, websites and articles, so was looking for general advice and guidance from those who have done this for a while,

My brain is going to be a sponge. Hit me with advice. Thank you!
