The jumping castle operator accused in the Hillcrest Primary School tragedy will face a hearing in the Devonport Magistrates Court next month.
Rosemary Gamble, owner of Taz-Zorb, has pleaded not guilty to a single charge of failing to comply with health and safety duty under the Workplace Health and Safety Act.
The charge falls under category two, indicating that the alleged breach of duty put people at risk of serious injury or death.
The incident on December 16, 2021, saw a strong wind gust lift a jumping castle containing several children into the air.
It tragically resulted in the deaths of students Zane Mellor, Peter Dodt, Jalailah Jayne-Marie Jones, Addison Stewart, Jye Sheehan and Chace Harrison.
Three other children were injured.
The hearing is scheduled to run from November 5 to 15.
