[nznog] Does anyone sell upload favorable international transit in NZ?

From what I understand, most bandwidth purchased from the Southern Cross access cables is purchased in symmetrical quantities. ie 1gbps in both ways.

Given that a lot of this is sold to residential ISPs with download favorable profiles, do any of them resell transit at a lower cost with a high up to down ratio (ie 1 gigabit up, 10 down or something similar)?
