Can rural and regional areas get Freeview?

Yes.

Freeview is available via satellite and via UHF.  This is the most cost-effective solution for New Zealand, given its topography and population, and ensures we have a robust, reliable, secure, and modern broadcasting system.

Satellite coverage reaches nearly 100% of New Zealand homes and can be received using a Satellite Dish (a working pre-existing satellite dish will work) connected to a dual tuner TV, satellite box or satellite recorder with Freeview.

UHF coverage is available to about 87% of New Zealand homes and delivers HD programming as well as regional channels.  It can be received using a working UHF aerial connected to a TV with Freeview, or a Freeview recorder or set top box for UHF.
