Sarah is a highly experienced advisor who quickly gets to grips with complex issues, frames them in strategic terms, provides advice on practical solutions. She takes a multidisciplinary approach which makes both her both highly effective and extremely versatile.

Sarah is an experienced and trusted advisor to senior managers, chief executives, board members and government ministers in both New Zealand and Australia.

Originally a Treasury-trained commercial regulatory economist, Sarah has moved in and out of the public and private sectors where she has gained experience in water, energy, transport, labour market, health and social services.

Sarah has often been called on to lead some of MartinJenkins’ most complex and high-profile independent reviews and investigations. She combines outstanding analytical abilities with a strong set of strategy-shaping, problem-solving and communication skills. Clients value her ability to provide independence while also working collaboratively with the organisations under review and other stakeholders. 

Relevant examples of Sarah’s work include:

  • Independent review of Chorus NZ’s next generation network contracting model. This review took place over multiple months and involved working collaboratively with Chorus and associated service companies in relation to allegations of worker and migrant exploitation in the Chorus supply chain

  • Successfully leading business cases including a recent example that secured $100 million to support large-scale environmental remediation for a joint venture of three Councils and multiple iwi groups

  • Appointed as Chief Advisor to a large State Sector Inquiry into the use of External Security Consultants by 132 individual entities under review. Sarah devised the review method, individual lines of inquiry and co-wrote the Inquiry report

This includes leading budget and financial advice to state-owned enterprises and government departments, completing commercial transactions on behalf of the Crown, playing lead analytical roles in major policy initiatives including in the transport, energy and telecommunications sectors.
