Have called them with absolutely no success. Their position is that I have redeemed 2 one-ways and they are sticking to it. I'll try writing to Customer Service. Thanks for your input, I'll be heading for the airport shortly (journey begins in AKL) and I'll report back with any further news when I get back from my trip.
