(Sorry if this the wrong thread....)

I'll be transferring a significant amount from NZD to AUD within the next month. I've never used a fx broker before so I'm not sure what the potential risks are but I'm nervous about that "fraction of a second between the money is taken from one account in NZD and deposited in another one in AUD"... if you know what I mean.

Would anyone recommend a reputable broker? I've heard of HiFX, any references on them?

Thanks in advance.
