The jury took under three hours to find him guilty on all charges.
In his opening address to the jury, Crown prosecutor Gareth Kayes said that on March 12 last year, staff at Waiuku College woke to an email that had been sent at 1.42am.
“It was titled ‘Important: Don’t come to school tomorrow’. And it started with the words ‘This is my manifesto’.”
The email spoke of being bullied and humiliated by teachers at the school, being unfairly treated by police and being made to feel like a second-class citizen for being Chinese.
“I am going to do something about this now. I have began [sic] preparing for doing something about this since February this year and have finished now.”
The email went on to set out in some detail the preparations the sender said they had made to carry out attacks on Waiuku and Rutherford colleges, as well as damaging the Pukekohe and Te Atatū police stations and buildings at Parliament.
That included making firearms using a 3D printer and creating bullets and explosives to be used in an attack.
The sender said they wanted to kill more people than the Christchurch mosque terrorist, who murdered 51 innocent people on March 15, 2019.
“Do not assume that my guns will not work or are fake because they are 3D printed, that will be very bad.”
The email was purportedly sent by a female former Waiuku College student, but after she allowed police to examine her electronic devices, officers established this was not the case, and their inquiries led them to Huo.
Huo is due to be sentenced in October.
