Police said the alleged threat to kill was made between July 17 and September 7 of 2021.
In November of 2021, the man appeared again in North Shore District Court facing a further six charges of possessing objectionable material.
In November of 2021, not guilty pleas were entered by counsel on behalf of the young man for the charges.
The man was first granted name suppression in 2021 after his lawyer Peter Syddall argued name suppression was needed to ensure his client had the best chance of de-radicalising.
