Given that first-home withdrawal isn't an option, let's look at the member tax credit. This boils down to money from the Government for everyone in KiwiSaver between the ages of 18 and withdrawal eligibility - generally 65.
Up to $521 is paid each year to KiwiSavers who contribute $1042 to their accounts. Adding $1042 is about $20 a week, but if that is still a stretch, the member tax credit is 50 cents on every dollar you contribute up to that $1042 mark.
The calculations are made on contributions between the start of July and end of June every year and your provider should update you on whether you have contributed enough to get the full member tax credit well before the end of the "KiwiSaver year".
Over time the member tax credit can make a real difference. The Commission for Financial Capability - the organisation behind the Sorted website - has run a couple of calculations.
A 30-year-old earning $50,000, contributing 3 per cent, matched by their employer, would have $196,215 by age 65.
Without the member tax credit the balance would be $175,607 - a difference of $20,608. The member tax credit adds up to $18,219, plus $2389 in investment earnings would be missed.
A 50-year-old on $80,000, contributing 3 per cent, matched by their employer, would have a balance at age 65 of $81,889.
Without the member tax credits, the balance at that age would be $73,945 - a difference of $7944 made up of $7821 from member tax credits and $123 in investment earnings.
Not to be sniffed at, I reckon.
