Both you and your 'friend' (referrer) will receive $20 (Doesn't state a max but last year the max was of $60 per person) when you enter the special code in the app or online.
Here's a screenshot of the details (with unique code blanked out) https://files.cheapies.nz/upload/1302/2190/img_20180703_2218…
go to the co-operative bank website homepage co-operativebank.co.nz the promo code box is on the left hand side - enter it in there :) (this is what co-op told me, upon looking at it, if you are on mobile, scroll down (it isn't on the left) until you see "Promo code" (this was the case for the last one, not sure if it is true for this one, I found mine in the Co-operative report they send as pictured)
The promo code can be entered on left side within app (or when signing up, sorry I can't remember specifics)
Students have no account fees, and will receive the yearly rebate, so win-win
does anyone know how much is that "yearly rebate" they give? what was the previous few years amounts?
