I don't think there is any program that would get you a mid-tier status (all alliances: *A, OW, ST) in a single round trip in business class (with an exception to ATW) from the scratch.

You could become Ruby with OF's program, as suggested by inasmuchas, you need to have 4 base QF flights (QF codeshare also works). Since you seem to fly NZ the most, I suggest that you just bank your miles with CX (Asia Miles)... and not worry about achieving status (unless you intend to fly more OW in the future).
