NZ Book Month is back with the same plan it’s had for the last seven years: to promote books, reading and literacy amongst all Kiwis, young and old. To do this the organisers are repeating last year’s Books Change Lives campaign, and distributing more than four million $5 vouchers, aimed at putting a book in the hands of every single New Zealander. This simple idea got extraordinary results last year, when New Zealand was the only country in the developed world where book sales rose rather than fell.
