I sent a update request thru this morning outlining the missing junctions & road not connected, hopefully they get onto it quickly.
NZTA uses Google base maps also, they have been on my case as well to get it sorted.
Waze is owned by Google, but two different operations. Data sharing is Waze -> Google but not in reverse.
Waze has the most up to date maps as it is community driven.
