Rotorua primary school principals are increasingly concerned about the video game Fortnite as it affects some pupils' school work.
The game was first released in 2017 and it's estimated there are 125 million players worldwide. The online multi-player game can be played on Playstation, Xbox and on smartphone.
In Westbrook School's most recent school newsletter principal Colin Watkins said the school was becoming "increasingly aware of and concerned" about children playing the game.
"This game is recommended for those 12 years and older and seems to be extremely addictive. Many children are staying up late and spending many hours on the game each night.
