The 2016 "Model of the Year", shared with her almost 50 million Instagram followers her anger towards the disrespect and violence 17-year-old Hoda Al-Jamaa experienced.
"It makes me angry and sick to my stomach," Hadid said. "We need to change this mindset of immediate judgement."
Hoda was sitting with her friends at Otago Girl's High School when three other pupils asked the girls how to swear in Arabic and started taunting them.
The situation escalated and Hoda ended up in hospital after she was beaten and had her hijab ripped off while others filmed her.
"Teach our friends, children, parents, families that wearing a hijab, being Muslim, or being anything other than white in general, does not equal being a threat or different than anyone else. Teach them to love before hate. To educate before judgement. To protect before bullying."
In the post, Hadid expressed her sympathy and support to Hoda and her other Muslim friends who were also attacked.
"I am so sorry to the ones that have felt this kind of disrespect. You do not deserve it," Hadid wrote. "Keep your faith. Love your God. Be you. And the ones who appreciate and love you for YOU are the only ones that matter."
"It’s not you, it’s them. Remember that. I love you."
Hadid is open about her Islamic faith and says she is a "proud Muslim". She was born in the US, but her father is Palestinian and her mother is Dutch.
She is an avid advocate for Muslim rights and has recently been in the headlines for slamming countries that are not allowing women to wear hijabs.
Hoda's story has been seen around the world, with many sharing their experiences, support and offering sympathy.
A petition on Change.org has been launched to demand Otago Girl's High school to address the incident with almost 50,000 signatures at the date of publication.
"There is no room left for hatred and bigotry… Schools must take responsibility for addressing bullying and racially charged verbal and physical abuse," the petition states.
"Let's stand together to bring justice for Hoda and the other Muslim girls who were attacked."
Otago Girl's High School issued a statement on Facebook on Friday evening regarding the incident.
"As a School Board, we take very seriously our responsibility for the emotional and physical safety of our students, staff and wider community," the statement said.
It said following the investigation into the attack, the school board completed its formal disciplinary process around the incident, working closely with the Ministry of Education and police. The school said they can not share the outcomes but are confident the appropriate steps have been taken.
"We all need to do our part to protect young people, whether it is to heal or learn from their mistakes, so we ask everyone to respect the confidentiality of the process and the privacy of those involved.
The school has put in place "significant" pastoral care systems since the incident occurred, which included often low-level check-ins and monitoring by teachers and deans of students, with more tailored and extensive support available as needed.
The statement said an email had been sent out to parents and caregivers on Thursday by the school's principal addressing the matter.
