Workbase chief executive Katherine Percy said most people did not know that more than 40 per cent of adult New Zealanders - including those with jobs - had poor literacy or language skills.
"Workforce literacy issues are often overlooked because most adults with significant literacy and numeracy gaps can still read and write to some extent," Ms Percysaid.
The idea of reading for enjoyment was something new for many people who had already started the programme, she said.
It was also helping families in other ways.
"A lot of people are using their newfound skills to read to younger children."
Auckland Airport spokesman Charles Spillane said Workbase was a worthy cause as those within the wider community would also benefit.
