200 people are expected to attend each of the two Park Up For Homes events tonight.

One is being held at Wellington Cathedral, opposite The Beehive, and the other is taking place at the Otara Town Centre carpark in Auckland.

They follow one in Mangere last week that attracted around 1000 people.

Child Poverty Action Group housing spokesman Alan Johnson said it's a chance for people to make their voices heard.

"If you're not happy with the way in which we're failing many tens of thousands of children with their housing, then just come up and participate in a quiet, peaceful protest."

Mr Johnson said it's also a chance to show support and acknowledge those who are doing it tough, living on the streets and in carparks.

He said ordinary New Zealanders are now starting to understand the problems poorer people are facing.

"And I think they're becoming more concerned about that, and I think that's starting to change the political response to this."

Another Park Up For Homes event, organised by boxer David Tua, is scheduled for Onehunga on the 2nd of July.

Others are in the pipeline for Napier and Papakura.
