I've got a Huawei P6 that's just under 2 years old, it has recently started to intermittently reboot by itself. This happens at random intervals and can occur multiple times in an hour but then go a few days to a week without doing it at all. 

Sent away for warranty assessment through 2Degrees and repairer claimed it is water damaged beyond economic repair. I've never dropped it in water or anything like so uncertain of how (I presume though use in rain over the years?). No charger included, light scratches on rear of phone, screen is in good condition with no scratching. 

Also available is a prepay $29 promo sim I received when purchasing another phone, see here for details: http://www.vodafone.co.nz/simpromo/ , willing to give sim away for free including postage if needed via envelope. 

Pickup Wellington CBD or courier anywhere in NZ for $5. 

Any questions post or PM me.
