Extended to multiple rooms
 
Outcome of investigation: 

The batteries purchased online were a replacement, resulting in the homeowner using a charger intended for batteries with different specifications. Lithium batteries are extremely volatile and should only be used with the correct charger intended for its specifications.

Because the batteries were purchased overseas (outside of NZ jurisdiction) WorkSafe Energy Safety was unable to conduct an audit on the supplier. The case was closed on that basis.
