She has been invited to help shape the world's future through the development of new policy.

Ms Homaei will remain in New York for six months as part of a team representing the world's most fragile and disadvantaged states.

Haleh Homaei had earlier worked with the UN, initially on behalf of Timor Leste, in 2012.

“I’m so humbled to be asked to be part of this historic process,” Ms Homaei said. “Our shared purpose is to transform lives and save the planet.”

Haven; Home, Safe CEO Ken Marchingo said Ms Homaei's previous work with the UN concentrated on "the places that have the least democracy and the most problems".

Mr Marchingo said Ms Homaei would work to ensure those places had a voice in the UN's post-millennium development plan.

"We spend a lot of our time working with individuals who are often victims of structural problems and we look for opportunities to change the structural problems," he said.

"This is an opportunity for one of our staff to do that."

Mr Marchingo said Ms Homaei had skills well suited to the task of negotiating new policy.

Haleh’s work at the UN will focus on research, draft report writing, attending inter-governmental negotiation meetings, and lobbying for support and understanding on issues related to the fragile states.

“I am thrilled that Haleh is seen by some of the world's foremost experts on the elimination of poverty and disadvantage as the right person to help deliver this agenda," Mr Marchingo said.

“We all know that one of the real secrets to generational changes in poverty, disadvantage, and homelessness is structural and the key to that is policy.

"The key to policy is governments and often multi-government agreements and action."

Mr Marchingo said Ms Homaei's skills were of great assistance to the work of Haven; Home, Safe.

Ms Homaei joined the Haven; Home, Safe team in the middle of 2014.
