The recent addition of cellphone coverage in remote parts of South Westland has also introduced the area to a problem experienced everywhere - people driving while on the phone.
Small cell towers have been erected at Haast township, Roaring Billy car park, Pleasant Flat, Lake Moeraki, Bruce Bay and Lake Wahapo.
''There have been several crashes directly next to these sites recently and the cell coverage is gold,'' Senior Constable Paul Gurney, of Haast police, said.
But the towers were small and only covered about 50m, so people had to stop their car. The Haast tower covers a wider area with a 4km radius.
''We are hoping they'll be getting on to building the more permanent sites for Haast (Haast Junction, Okuru, Hannahs Clearing and Neils Beach/Jackson Bay),'' Mr Gurney said.
