Ash cloud from chile stopping international flights in New Zealand?

I'm supposed to be flying from auckland airport in new zealand to london in england next monday (the 27th), and am wondering if anyone knows if flights are being canceled internationally or just ones from australia to new zealand and vice versa. So far they just seem to be talking bout flights to lower australia. My airline I'm flying with is royal brunei airlines. So has anyone just recently flown to london from NZ or from NZ to london? or anyone know bout what flights are being affected and how long roughly the flights will be down?
