Six topless schoolgirls on dirt bikes rode on the grounds of Hamilton Boys High School as an end of year prank, which ended with one student injured.
Tauranga schoolgirls have dashed through Tauranga Boys' College in minimal clothing, carrying out their own version of an undie run today.
A group of girls dashed across the Tauranga Boys' College's field between Cameron Rd and Devonport Rd in various states of undress. Some wore shirts, skirts and pants whileothers were in their underwear.
A police spokeswoman said police had received a report about groups of schoolgirls heading to the boys' school to cause mischief.
A bystander said he saw about 20 to 30 teenage girls running across the field.
The incident is the latest in a string of end-of-year pranks attracting attention throughout New Zealand.
Last week, a group of topless Hamilton schoolgirls rode dirtbikes through a boys' school. One of the bikes ran a boys' student over and injured his leg.
At Bethlehem College, a group of students wearing animal masks and carrying water guns were likened to Islamic State (ISIS) during their school's end of year prank.
