The spark for the current bout of protests came after a torn-up copy of Sri Guru Granth Sahib - Sikhism's holy book - was found in the village of Bargari.
The alleged desecration of the holy book angered many who came out to protest in Behbal Kalan, a nearby village, last Wednesday.
As tempers soared, police opened fired. Two protesters were killed and dozens of others wounded.
Ripudaman Singh, who also took part yesterday, told the Rotorua Daily Post the students feared for their family members in Punjab.
"Sikhs are being killed for a silent protest ... We just want justice ... We feel that our religion is not being treated the same as others such as Hinduism. We want equal rights for our religion too."
