I bought into XRO at just over $NZ6 in late 2012 and have been holding ever since. I've just moved my holding over to the Aussie section of my portfolio - makes my ASX results look quite respectable now and camouflages the disaster that a few Oilers have proved to be over the years. Still holding those though waiting for a miracle to arrive.
Looks like the ASX is happy to have a few more Kiwi holders on board now - XRO SP is up $1.92 as I write. I'm not too distressed about that - and Rod Drury is probably moderately happy too. Early days of course, but he may have proved a few naysayers wrong.
