i actually had luck getting a NZ segment credited.. my MP number fell off after being rebooked due to irops in AKL. took months, but after i faxed in for the second time i called MP after a couple of days. they told me that it had been sent to NZ and that there would be a response in a 60 days. my credit just showed up ~45 days later. i did, of course, have my BP...
this is what put me over the threshold for 1P, so i would have been rather upset without the credit.
