Katie Phillips



I am a Chartered Management Accountant with almost thirty years of experience gained across multiple finance, risk and performance roles in the UK, Australia and New Zealand.

Before joining the Public Sector 3 years ago, I spent most of my career working with Global and Domestic Banks, focusing on capital management, leading through change, balance sheet risk management and commercial risk. Currently I am the Head of Risk for Capital Markets at New Zealand Treasury, with the scope of my role extending from Market and Liquidity Risk through to Strategic and Operational Risk.

I am passionate about bringing people together to share knowledge, and resetting the role and perception of risk from that of a backward looking compliance function, to a forward focused value add service that delivers positive, sustainable and long term business outcomes.

I moved to New Zealand 6 years ago from Chester in the UK, with a couple of years in Sydney in between, and now live in Wellington with my husband and our two teenagers. I love that you can walk everywhere, that we are surrounded by water and hills, and that you have a pretty decent music scene.

Jane Rollin

Management Board


I’ve held a number of roles in the UK and in New Zealand that on the surface seem wildly unconnected, but are strongly invested in building enduring relationships; communicating complex matters simply; connecting people and issues; risk based thinking and managing the unplanned – all with the aim of ensuring good decisions are made that consider a wider context.

I’ve held prior roles within the oil industry; local, regional and national government organisations; management consulting, crisis and emergency management and more recently as the GM Risk Integration within Fonterra.  I have just returned to the Ministry of Civil Defence and Emergency Management to continue my ‘resilience’ journey.

Duncan is the Manager of the Risk Team at MBIE. Duncan has always been fascinated by what makes organisations succeed, and has found that good risk management is essential to organisational success.

Duncan won Risk Professional of the Year at RiskNZ’s 2019 Awards of Excellence for his work in revitalising Wellington City Council’s Risk Framework through his customer-focused engagement with the Executive team, the Audit and Risk Committee and the wider organisation.

Away from Risk, Duncan is a proud citizen of Upper Hutt. He is a middling gamer, guitarist and football player.

Feel free to reach out to him.

Imogen Perez

Management Board


I am currently a Principal Risk Advisor within the Enterprise risk team at MBIE. In this role, I have been fortunate to meet many other risk practitioners from other Government agencies through my active involvement in the Public Sector Risk Forum (PSRF).

Prior to joining MBIE, I was at ACC for 3 years. When I first started at ACC, I was managing a large operational team within Medical Provider Registration Operations space, before moving into the Enterprise Risk management team.

Although I have spent the last five years in the public sector, I have over 20 years’ experience within the banking sector at both Kiwibank and ANZ (including The National Bank of New Zealand). In that time, I had a number of roles across, Retail, International Trade & Finance, Payments, Business Services and within the second line Risk Management team (Manager Compliance Framework & Policy).

Throughout my career, I have moved from operational management roles to specialist roles, with risk management being my specialty of choice (last 13 years). I really enjoy helping the business become successful by weighing up the risk of the decisions they make. To do this I think it’s important to keep learning and stay fresh in understanding the difficulties and challenges that our stakeholders face. For me this is having regular stints within the first line business – so I can understand their pain points.

I also really enjoy people leadership and creating a thriving and engaging work environment. I am proud to see people that I’ve previously had the pleasure of managing move onwards and upwards in their career journey.

I have a pretty active home life with two kids still at home (15 and 12 years). I am pretty active supporting their activities, and am a pretty vocal cheerleader (from the side lines), I also manage a few sports teams they are involved in.

Lynda McCalman

Management Board


I am a senior executive leader and trusted business advisor with 35 years Risk and Compliance, and Crisis Management experience.  I have worked globally across many countries, returning to NZ in 2015.

I am the Risk and Assurance Manager at Hancock Forest Management (NZ) Limited, a forest management company responsible for managing some of the finest and largest forestry assets in New Zealand on behalf of a global mix of investors.  My role includes oversight of the enterprise wide risks associated with all plantation forests being managed.  

Prior to joining Hancock, I worked in horticulture for two and a half years with New Zealand Kiwifruit Growers Incorporated.  As the Performance and Supply Manager, my role was to monitor the marketing organisation Zespri and industry performance to ensure it operated in the best interests of all kiwifruit growers. 

Earlier I rose through the ranks at PricewaterhouseCoopers (PwC), commencing my career in the audit practice, then later working in various countries globally in Risk and Compliance, and Crisis Management roles.  The last eight years of my career with PwC were as the Risk, Compliance and Regulatory Partner, based in Dubai, with responsibility for 12 countries within the Middle East Region.  

I am a pro-active and results oriented individual who enjoys working with management and staff to articulate the vision and direction of an organisation.  To this end, I am passionate about improving the knowledge and practice of risk management in NZ such that we are globally recognised for our understanding and articulation of risk in an evolving world.  In today’s changing landscape of population growth, rapid urbanisation, and climate change (to name a few), creating and communicating risk information faster and at lower cost, improving the quality and transparency of risk information, and enabling more local engagement in the production of authoritative risk information than ever before underpins our success.

I live and work in Tauranga, Bay of Plenty.  In my personal time I greatly enjoy the outdoors and you will often find me hiking our wonderful walkways in NZ.  I am also an avid reader and reviewer of books.

Vaibhav Bhatnagar

Management Board


I am currently working as a Risk and Resilience Advisor at Watercare Services and have been in this role for the past two years. I have a Master’s Degree in Business which coupled with my previous experience in Insurance and Risk Management, assists with my current role working on business continuity, risk management and building resilience. I am perusing my professional qualification with the IRM, results awaited. My work experience has helped me view the business from many different perspectives, which will help give me a rounded view of risk management within Watercare.

My career in Risk Management started in Perth in 2009, where I was a Business Analyst for Curtin University where I was one of the first implementors of the ISO 31000-2009 standard. From there I moved to a role in Insurance where I was a founding team member of the claims team for a Health Insurance company called Religare Health Insurance. Working for a startup gave me first hand insight and understanding at the challenges and hurdles faced when starting a company in a highly regulated industry. My role progressed, and I was managing the Investigations team and worked on implementing an early detection framework and investigation of reviewed value claims.

I joined the Watercare in 2014 working in the Customer team and was highly involved in the analysis of customer interactions which was used for training and process improvements. I joined the Risk and Resilience team at Watercare in 2017, and my work included updating Watercare’s incident management plan, business continuity plans, and development of the resilience programme.

I am a strategic thinker and problem solver. I like to work on complex challenging issues, break them down and addressing concerns of the many stakeholders involved. I have been able to use this in developing challenging scenarios for business continuity testing and in turn building robust continuity plans.
