When it comes down to the consent, does Spark/Enable take care of this or is the customer's responsabily? 

I'm on a cross-lease section with shared driveway. The other property is a rental but I know the owners well (although they don't live in ChCh).

Last update I received from Spark was on March 14th. (Received the Huawei Router on the same day). Have already called Spark to get an update but they couldn't give me any more info. Would contacting the other party speed things up?
