Ms Hassock is one of more than 1000 supporters nationwide expected to join the vibrant, fun collection where people don animal costumes and hit the streets on December 19 and 20.
All money raised will be used to fund campaign initiatives and humane education projects next year.
"I've been volunteering for SAFE for some time now, doing all manner of things to help animals. I feel that their work is vitally important to help spread the word so we can make things better for animals who are suffering," Ms Hassock said.
With no external funding, SAFE rely heavily upon generous members of public to put their hands up and give up their time, executive director Hans Kriek said.
"As well as raising money to help animals, SAFE's appeal is lots of fun, with communities from all over the country coming together to show their compassion... It's inspiring to see and we're so grateful to those who donate and volunteer."
Hawke's Bay residents who would like to get involved for as little as two hours, can register at safe.org.nz.
