"There have already been four children killed this year through child abuse and we are only in the sixth month," she says.
David White, whose daughter Helen Mead was killed by her abusive husband, will attend the ceremony. He is an ambassador for White Ribbon, an organisaton against domestic violence.
White Ribbon Bike Riders are riding from Wairarapa and Tauranga for the event.
The solemn occasion will begin with karakia (dawn prayers) led by the Mana Whenua. Marama Hetaraka and George Ngatai, SAFVPN co-chairs will read out the names as candles are being lit.
Maori Party co-leader Dr Pita Sharples and NZ Police Superintendent John Tims will give short speeches.
Ms Bhana says this vigil is similar to the one held five years ago and they are now hoping to make it an annual event.
"The 100 plus names that will be read out are 100 plus too many that have been killed through child abuse and domestic violence," she says.
