Hassouna was born and raised in Egypt but moved to New Zealand in 2013.
He settled here with his partner and son and began working as a filmmaker while learning English.
But soon after arriving, he decided he wanted to become a cop - and set about improving his fitness and gaining confidence in the language. Hassouna became even more determined to join the police after last year's mosque attacks in Christchurch.
When he started his first shift on Monday he was assigned to the reassurance team and sent to West Auckland to patrol the community.
The team's main role is to educate the public on the lockdown - what the rules are and why they are important.
"We're stopping vehicles and making sure people are aware of the situation, ensuring compliance," he said.
"We educate people about their bubble. The majority of people are compliant but we have come across some people breaching the lockdown rules.
"Overall, everyone is being cooperative."
Hassouna said he was "pretty surprised" as he had expected more breaches and more attitude towards police.
"But the vast majority we come across are good, the vast majority thank us for being out on the frontline, and doing our job and looking after them," he explained.
"But overall they are happy to stop and talk to us, they are cooperative and they don't get angry or upset."
Hassouna had been called to a few parties by neighbours concerned about bubbles being breached and annoying noise levels.
He's also been swinging past supermarkets to make sure queues are orderly and people are social distancing.
"But there's been nothing serious, so that's good," he said.
"There have been no reports of family harm (for his team), there has been a decline in serious incidents and dishonesty. I wish it would stay that way after the lockdown."
Hassouna had Good Friday off, but was back on the beat for his weekend shifts.
