Hi Everyone -

(Wasn't sure where to post this - so please bump if need be).

I'm basically looking for the best way to find a rather strange route. I've used ITA, Google Flights, and Skyscanner, but am wondering if I'm missing some tricks to drop the fare even lower. Basically, I'm looking for a route that starts / ends in Perth and includes an 4-8 hour layover in Wellington, a 2-3 day stopover in Sydney (well, Newcastle would be even better...), five days in Kona, and three weeks in SFO. Any other necessary stops are fine.

This is a version of the routings I've found - but I feel like there may be a way to include long layovers and I just don't know how?
