The story is a bit misleading. The area covered by the street a day scheme is a small part of the North Island, which is the area served by UltraFast Fibre. In most of NZ Chorus is well advanced in rolling out fibre to the premises.
And Spark is now a minority telco, there would be few streets in NZ where Spark has most of the retail customers, let alone all.
Register, you have polished up a press release t#rd, shame on you.
