The electorate office of Corrections Minister Sam Lotu-Iiga has been vandalised with paint as a protest over the treatment of transgender prisoners.
The attack took place overnight at the Maungakiekie MP's Onehunga office, leaving a large red paint mark on the front window.
Several copies of a note were glued to the window, which claimed Lotu-Iiga had "blood on his hands" due to Corrections' handling of transgender prisoners.
"This week is Transgender Week of Awareness, and transgender women in this country are systematically endangered by the placement policies of the Department of Corrections," the note read.
The note referenced the alleged rape of a transgender inmate in Mt Eden Prison reported last month. Lotu-Iiga had "refused to take responsibility," it read.
