Need help hedging Exotic Pairs

I need help computing some exotic currency pair hedging.

Example:
How can I hedge Long 1 LOT GBPNZD using GBPUSD and NZDUSD?
How much lots should be traded to come out with a perfect hedge?

PS. I dont want to hedge it using correlation...

Here I have my opinion.

In short, the answer seems to be " No Way", sorry, but so far this is my conclusion.

Good-day,
The only way is the 3pair hedging.
In this order: GBPNZD,NZDUSD,GBPUSD - You either Buy,Buy,Sell or Sell,Sell,Buy in that order.Check the link below for more clarification and my last post.
