A group of Christian leaders who have chained themselves to Nicola Willis' Johnsonville electorate office are vowing to stay there overnight.

They want an urgent timeline from the Government for implementing sanctions against Israel over the war in Gaza.

Reverend Mel McKenzie says they're fasting in solidarity with the people of Palestine.

"We're just so focused on the suffering that's happening in Gaza and we're doing what Anglican and Catholic priests do - which is to pray and fast."

Nicola Willis says she supports the right to peaceful protest - but adds their presence is blocking the public's access to her office and its staff members who would otherwise be able to provide help to the community.

Five clergy were trespassed from Simeon Brown's Pakuranga electorate office earlier today.
