Out of the blue, Google has posted the official factory image for Android 4.4.4 Release 2 on the Nexus 5 on their site. The update is currently rolling out right now in New Zealand, Australia, and India — but that’s as far as it’s going.
This is essentially the same update we received everywhere else last month, only with specific radio updates tailored to the networks in these regions. In fact, the factory image even lists off a specific carrier in New Zealand (2degrees Mobile). For those with knowledge in these things, the downloads are linked below.
