Associate Professor Hanna Wilberg
LLB(Hons) BA (Otago), BCL MPhil (Oxford), Barrister and Solicitor (NZ)
Hanna Wilberg’s research interests are mainly in Administrative Law and the Tort liability of public authorities, but also range more widely across Public Law. She is currently writing a book on The Principles of New Zealand Administrative Law, to be published by Hart in 2021. She is also the New Zealand Law Review’s contributor of scholarly reviews of recent developments in Administrative Law; and a contributor on New Zealand developments to the International Survey section of Public Law. Her publications include a collection of essays co-edited with Professor Mark Elliott (Cambridge), entitled The Scope and Intensity of Substantive Review: Traversing Taggart’s Rainbow (Hart Publishing, 2015); and two special issues of the New Zealand Law Review which she commissioned and guest edited: part 1, 2016 on NZ Administrative Law and part 2, 2010 on Proportionality, Deference, Wednesbury: Taking Up Michael Taggart's Challenge.
Before joining the Auckland faculty in 2004, Hanna taught at Southampton University in the UK. She was a research assistant to Professor Paul Craig at Oxford; a Judges' Clerk for Richardson P and Tipping, Blanchard, Keith, Thomas, Gault and Henry JJ at the Court of Appeal in Wellington; and practiced law at the Crown Law Office.
At Auckland, events that Hanna has organised or co-organised include a workshop on Jerry Mashaw's new book Reasoned Administration (February 2016), the NZ Administrative Law conference and workshop (January 2015), the LRF conference on Judicial Review in Commercial Cases (2011), a NZ Public Law Colloquium (2011), and a symposium on Public Law in Three Nations (2010). She served as the co-editor of the New Zealand Law Review from 2008 to 2013; and as the Associate Dean (Equity) in 2017-2018.
Hanna was a Herbert Smith Visitor at the University of Cambridge in 2014, a visitor at the University of Toronto in 2014, and a visiting fellow at the Australian National University in 2007.
