With 24 years of dispute resolution experience,  I understand the time, cost and resource disputes can consume, not to mention the stress an active court proceeding can cause for you, your business and your family.

Mediation is a safe and effective way to get to the heart of the issue and to explore resolution options before getting entrenched in costly battles.

Importantly, I recognize that in mediation, the parties control the outcome of the dispute in a way that provides certainty in a cost-effective manner.

A founding partner of Ford Sumner, I have practiced in dispute resolution including, employment, contract and commercial, company/shareholding, insolvency and creditor remedies, and related areas for over 24 years representing a range of local and international clients both private and public.

I have appeared regularly in specialist Tribunals, the District Court, High Court and Court of Appeal.  I have also appeared in and attended over 100 mediations.

I am an accredited mediator through the Resolution Institute, New Zealand and Australia’s leading resolution organisation.

I am available to act as mediator in a wide range of disputes, large and small.

Types of disputes mediated

  • Contract and Commercial Disputes
  • Employment
  • Shareholder, director and partnership
  • Wills and estates
  • Family protection and testamentary promises claims
  • Trusts
  • Insurance

Services available

  • I am happy to travel within New Zealand to act as mediator.
  • Alternatively, I can make the central Wellington offices of Ford Sumner available to the parties without additional cost or where appropriate, due to traffic light settings or parties preference, I can conduct the mediation on Zoom.

Cost and terms

  • A typical mediation involving two parties for a full day will cost between $4,000 and $5,000 (plus GST and disbursements), which includes preparation time and is usually shared by the parties equally.
  • Half day mediation costs start from $2,500
  • If there are several parties, or if the background material is significant in volume or complexity, you are welcome to contact me for an estimate of costs tailored to your dispute.
