Firstly I'm not connected with Raboplus so hopefully this post is OK.
At the moment Raboplus are giving away free money for opening a savings account with them. You don't need to do anything other than transfer an initial amount of $1 to them (which you still have - just at Raboplus) but you can get between $50 and $500 from the "Fortune Teller" on their website.
You don't have to make ongoing payments into the account if you don't want to use them or can't afford savings.
Unfortunately it is only open to NZ residents and you need to have a bank account to do the initial $1 transfer.
www.raboplus.co.nz (then click on the fortune teller banner).
I've managed to get $75, my OH $75, DS $50 and DD $100.
Which isn't bad for a few minutes work!
