British author, actor and comedian David Walliams is back in New Zealand to celebrate the release of his 10th children's novel, Bad Dad.

More than 150 young fans of the author waited up to an hour outside Whitcoulls in Westfield St Lukes in central Auckland to have copies of their books signed by the former Little Britain actor and writer.

Walliams' new book currently sits at #2 overall on the bestseller lists in New Zealand and he is the #1 top-selling author across all titles.

This is the second time Walliams has visited New Zealand to promote his children's novels.
