"People [who] wish to receive the White Pages Residential book can still get it – or they continue to look online – they simply have a choice of how they access the information."
Across the country the Yellow book continues to have high search and stable usage, equating to an average 9.6 million monthly look-ups, 65 per cent of which lead to phone calls to local businesses, the statement said.
Linton said the text size in the White Pages will be 10 per cent larger making it easier to read.
The new opt-in approach has been rolling out gradually in Christchurch, Waikato, Wellington, Otago, Hawke's Bay, and now Bay of Plenty.
However, the residential and business listings will remain combined in smaller regions more inclined to use the Yellow books – including West Coast, Whanganui, Timaru/Oamaru, Marlborough, Gisborne, Wairarapa, Manawatu, Southland, Nelson and Taranaki.
To opt in, Bay of Plenty residents can visit www.ypgbooks.co.nz and provide address details.
White Pages residential books are scheduled for delivery from July 27 onward.
