The Australian and New Zealand's currencies are heading for a weekly gain on Friday before a data showed that Chinese economy expanded at the fastest rate in a year in the Q4 and amid speculation that BoJ's monetary easing will increase demand for overseas investments. The Australian Dollar rose 0.1% to $1.0550 after touching the highest since January 11 at $1.0582 yesterday, while the so-called Kiwi fell 0.1% to 86.22 U.S. cents, but it has gained 2.3% since April 5.
