This seminar emphasizes the importance of data-driven approaches to measure positive social change and guide investment decisions in the social sector. Sir Bill English reflects on a decade of using measurement tools to improve policy and operations both within and outside government. He discusses tools that can bridge the gap between well-being policy and better outcomes for service recipients, especially in a tight fiscal environment.
It presents ImpactLab’s tools and methodologies for calculating SROI and measuring impact across various social programs and interventions. Sophie Kunze presents on measuring Social Return on Investment (SROI) as a guide for social investment decisions and operational improvements in the charity sector. She introduces the concept of social value and explains how SROI is calculated using three key drivers: scale, social value, and cost.
She showcases ImpactLab’s work, including:
Luke English provides an overview of ImpactLab’s housing work, which involves a Housing Impact Framework that considers housing interventions, population characteristics, investment tools, and related services.

This seminar discussed the role of tort law in addressing climate change. it discussed the current landscape of climate litigation, the role of tikanga Māori (Māori common law), and climate change as an intergenerational externality with potential market and regulatory failures. It examined an alternative view inspired by the Coase theorem, suggesting courts could internalize externalities and overcome obstacles to state action. It proposed the concept of “climate comity,” drawing from private international law principles developed by courts for mutual benefit. The seminar also discussed the suitability of tort law to impose responsibility for “unreasonable” emissions or recognise environmental rights, to provide judicial guardrails against inadequate government action on climate change.

This seminar explores whether New Zealand’s wholesale electricity market (WEM) is fit for the future as the country transitions towards a highly renewable energy system. It outlines the current WEM structure, including the spot market, hedge market, and ancillary services market. It examines anticipated changes in the physical electricity system, such as the increasing share of intermittent renewables like wind and solar, the growth in distributed energy resources, and the rising demand due to electrification.
It argues that a market-based approach is preferable over centralized approaches as it promotes competition, innovation, and investment efficiency. It proposes recommendations for “WEM 2.0,” including measures to improve accurate pricing, risk management tools, competition, and public confidence. It emphasizes the importance of capturing innovation and enabling demand-side flexibility to optimize the renewable energy transition while maintaining a reliable and cost-effective electricity supply.

Congratulations to James Sinclair and many thanks to Bryce Wilkinson and the other judges for their hard work.
Society is facing many seemingly intractable problems: climate change, mental health crisis, pandemics, wars. Charities and the not-for-profit sector make an important contribution in addressing those problems. They strengthen communities, improve social cohesion and deliver social benefits that complement actions by business and government. Charities play a key role in upholding liberal democratic values.
In order to thrive, the charities sector needs an appropriate legal and economic framework. However, it is often misunderstood by commentators and policy makers. Recent developments in New Zealand and around the world create serious risks for the health of the sector.
In her talk Sue Barker will cover topics including: the role of charities in democratic societies, recent developments overseas and in New Zealand with regard to how governments approach charities and the risks they create, what a world-leading legal framework for charities might look like.
This is an online only event. The speaker will talk for 40-45 minutes followed by some time for Q&A.
Sue Barker is the director of Sue Barker Charities Law, a boutique law firm based in Wellington, New Zealand, specialising in charities law and public tax law. She is a director of the Charity Law Association of Australia and New Zealand and a member of the Core Reference Group for the Government’s review of the Charities Act 2005. Sue is also a co-author of the text The Law and Practice of Charities in New Zealand (LexisNexis, 2013) and a contributor to Regulating Charities: the Inside Story (Routledge, 2017).
In 2019, Sue Barker was awarded the prestigious New Zealand Law Foundation International Research Fellowship, Te Karahipi Rangahau ā Taiao, to undertake research into the question “What does a world-leading framework of charities law look like?”. The report from the Fellowship, “Focus on purpose”, was released in April 2022 making 70 recommendations for charities law reform in Aotearoa New Zealand.

The winning entry this year was Nicholas Goldstein for his essay Five-Eyes, Spies, and International Ties: A Common Whistleblowing Regime.
Runner up was Connor Browne, LIFE’S NOT FAIR, BUT PHARMAC IS — DEFENDING PHARMAC FROM ITS CRITICS.
Congratulations to both winners and many thanks to Bryce Wilkinson and the other judges for their hard work.
LEANZ received 24 entries to the essay competition in 2020, a record number of entries. The standard at the top end of the submissions was very high.
The winning entry was Nathan Tse for his essay Decentralised Autonomous Organisations and the Corporate Form. This essay examined the role of decentralised autonomous organisations (DAOs) and asked whether DAOs really improve the corporate form. DAOs ostensibly eliminate agency costs due to the absence of a board of directors, automated governance mechanisms and transparency provided by the blockchain upon which the DAO is launched. Nathan’s analysis suggested several practical and legal obstacles that technological advancements and improved engineering must overcome before DAOs become a viable, mainstream organisational structure. Balancing the inevitable improvement in technology against these significant obstacles, this article predicts an incremental integration of DAOs into society through a hybrid approach, involving interim legal solutions and varying degrees of automation and decentralisation.
Runner up was Chanelle Duley, Democracy or Technocracy?: Policy Delegation and Populism? This paper identifies the incentives faced by elected and appointed policymakers and compares the efficiency of each policymaker’s performance under such incentives.
With thanks to Bryce Wilkinson, Lew Evans, George Barker and Bronwyn Howell for acting as judges.
