"The pilot and first officer were restricted from looking at the direction the laser came from due to the brightness of the light and the dangers of looking at laser lights," the summary said.
It was later established that the light was being beamed by someone at a party held in Howick.
When Hector was first spoken to by police, he admitted using the laser and pointing it at his friends and at motor vehicles, but denied pointing it at the aircraft.
Hector's community detention conditions included a curfew. If the conditions were breached, an 18-month prison sentence would be imposed, Judge Wiltens said, adding "there's no more partying".
Crown prosecutor Fiona Culliney told the court that the laser strike could have blinded the pilot and, because it happened when the flight was landing, had placed the lives of all on board at risk.
Judge Andree Wiltens said there was no doubt that alcohol was involved and Hector had admitted to consuming cannabis that evening - "a dangerous combination".
Hector had put the lives of 118 people at risk and if the aircraft had crashed into a residential area, further loss of life would have been likely.
