"By having the variety of comic themed activities at our LibraryPlus centres, we are allowing those who were unable to travel in to Hāwera for the day an opportunity to participate by dressing up, playing games and winning prizes."
Tyson, 7, and his brother Brax, 4, Langlands were two of the many tamariki making superhero masks.
Brax says he used gold glitter for his mask.
"I wanted it to be just like Iron-Man. If I had to choose he's definitely my favourite superhero. This mask will have the power to make me jump extra high on the trampoline."
Tyson says his favourite superhero is Spider-Man.
"I made my mask blue to match his suit. I also really like the Autobots from Transformers, especially Optimus Prime. I think they can be counted as superheroes as well because they helped to save the world."
