The Commerce Commission has released the first of three issues papers about the uptake of ultrafast broadband.
The $1.5 billion scheme will allow 75% of New Zealanders to access high speed broadband before 2020.
Telecommunications Commissioner Ross Patterson says he is unsure whether some consumers will be expected to pay to get the service if they are further away from a connection point.
"If they are, that will clearly be an impediment to those consumers taking up the faster service."
Dr Patterson says at present the scheme only allows for costs to be met if underground cabling is up to 15 metres and aerial cables are up to 30 metres.
Two other issues papers will be released, on 24 January and 7 February.
