But the trust warns there may have to be a cut-off, with unprecedented interest and registrations had passed 150 by midweek.
Special features will be the presentation of the Pilot City Trust's annual Unity Awards, with 11 people recognised for social and community work, the annual Robson Lecture, which will be delivered by Auckland University Head of Indigenous Studies Prof Tracey McIntosh, and a "Profile of an Activisit", paying tribute to trust stalwart Pat Magill, who at the age of 94 continues his advocacy and campaigning for social justice.
A book on his times and pursuits has been produced by daughter Jes Magill, who described it as a resource book, and "it's big and weighs 1.9kg". It will be launched later in the day at the Old Soldiers Club.
