An app has also been introduced to use with the programme this time, but it isn't compulsory - a good old fashioned paper version is also available
Participants can track their progress on the Reader Zone app and type in a code to register or in a log sheet which they can collect from the library.
For every 10 days of completing the 20 minutes reading, they receive one entry into the prize draw. If they manage to complete all 40 days, they will receive four entries into the draw for a range of different gift vouchers.
The challenge will help children keep up to date with what is new at the library, Kate says.
"This challenge encourages children to keep reading and come in to see our range of books, so they can choose ones that interest them."
Children can read non-fiction, fiction and graphic novels for the competition. Audio books and books read with parents and grandparents can be included - they just have to be books from the Stratford and South Taranaki libraries, this includes using our e-platform books as well.
The challenge runs from July 6 to August 28.
