cddt: There is a subset of landlords who wouldn't provide electricity connections or water connections if they didn't have to. The problem is that there isn't any requirement for landlords to provide infrastructure for telecommunications.
The nuclear option is to contact your local council and find out if their District Plan requires the provision of telco services. If it does, get some further details on that. They may enforce the developer to install it (at their cost). You may then also have remedies through the Tenancy Tribunal too.
