Anybody done any research on what is the best value phone card (e.g. Meihua, KiaOra etc) for making toll calls in New Zealand taking into account the various charges/fees (connection fees, service fees, call length surcharges etc)?

I've found Talk2U ( that looks pretty good - none of the above charges/fees and NZ toll calls at 1.9 cents +GST.  Haven't actually tried this one so don't know about the call quality though - a few years ago I think it wasn't good across the board with delays, echo's etc but I think quality has improved alot since then.

Anyone recommend any others?
