Services
I am Martin Dillon, a Hamilton-based barrister, commercial arbitrator and mediator practising independently from 109 Chambers. I provide legal and dispute resolution services in Hamilton and throughout the Waikato, including commercial arbitration, mediation, independent legal advice, investigations and criminal defence.
I am available for in-person work in Hamilton and across the Waikato. Arbitration and mediation appointments may also be arranged in Auckland, Tauranga and Rotorua. Suitable dispute-resolution, advisory and investigation work can be conducted online throughout New Zealand.

These services involve different professional roles. When appointed as an arbitrator or mediator, I act as an independent neutral and do not advise or represent either party. In advisory and criminal defence matters, I act for the client in accordance with the applicable terms of engagement and professional obligations.
Commercial arbitration
I accept appointments as an independent commercial arbitrator in commercial, contractual and civil disputes.
Arbitration enables parties to refer a dispute to a neutral decision-maker of their choice. It can provide a private, flexible and efficient alternative to court proceedings, culminating in a reasoned award that is normally final, binding and capable of enforcement.
I work with parties and counsel to establish a process proportionate to the value, complexity and urgency of the dispute. The procedure may include preliminary conferences, written submissions, document production, witness or expert evidence, determination on the papers, and online, hybrid or in-person hearings.
I accept appointments concerning general commercial disputes and matters involving technology, software, manufacturing, machinery and equipment, agribusiness, professional services, finance, insurance and logistics.
Commercial mediation
I act as an independent mediator in commercial and civil disputes where parties wish to explore a negotiated resolution.
Unlike an arbitrator, a mediator does not decide the dispute. My role is to help participants identify the real issues, communicate constructively, test their positions and consider outcomes that may be more practical than continuing with litigation or arbitration.
My approach is structured but flexible. Mediations may involve preliminary discussions, written mediation statements, joint sessions, private meetings and focused consideration of legal, commercial and practical interests.
I conduct commercial mediation in Hamilton and throughout the Waikato. I am also available by arrangement for in-person mediations in Auckland, Tauranga and Rotorua, and for online mediations throughout New Zealand.
Independent legal advisory services
I provide independent legal advice and opinions where a matter requires careful analysis, objective judgement or a perspective independent of an organisation’s existing advisers.
This work may include:
- written or oral legal opinions;
- assessment of legal and commercial risk;
- review of proposed decisions or courses of action;
- strategic advice concerning disputes or potential disputes;
- analysis of complex evidence or documentary records;
- review of organisational systems and processes; and
- advice to boards, executives, legal teams or other decision-makers.
An independent opinion can be useful where the issues are sensitive, existing advice needs to be tested, internal participants hold different views or an organisation requires a clearly reasoned assessment before making an important decision.
Engagements may range from a focused consultation to a substantial written opinion or multi-stage advisory assignment.
Independent investigations and reviews
I conduct independent investigations and reviews into serious, sensitive or complex matters where objectivity, discretion and procedural fairness are important.
An investigation or review may be appropriate where an organisation requires an impartial assessment of:
- allegations of misconduct or other concerning behaviour;
- governance or decision-making processes;
- compliance with legal or organisational requirements;
- disputed events or competing factual accounts;
- internal systems and operational failures; or
- matters carrying legal, regulatory or reputational risk.
Each engagement is governed by defined terms of reference. Depending on the assignment, the process may include document review, interviews, analysis of relevant legal or procedural standards, factual findings and recommendations.
My approach is systematic, evidence-focused and attentive to the rights and interests of those affected by the process.
Criminal defence
I maintain an established criminal defence practice and represent people facing serious or complex criminal allegations.
My criminal work includes:
- jury trials;
- judge-alone trials;
- pre-trial applications and evidential issues;
- bail and sentencing matters;
- appeals; and
- advice and representation throughout the criminal process.
Earlier in my career, I worked as a Crown Prosecutor. That experience continues to inform my approach to evidential assessment, trial preparation, prosecutorial decision-making and defence strategy.
Criminal defence work is conducted with discretion, careful preparation and close attention to the client’s rights, circumstances and understanding of the process.
Which service may be appropriate?
The appropriate process depends on what needs to be achieved:
- Arbitration may be appropriate where parties require an independent person to determine a dispute and issue a binding award.
- Mediation may be appropriate where parties want assistance negotiating their own resolution.
- Independent legal advice may be appropriate where a person or organisation needs an objective opinion, risk assessment or strategic recommendation.
- An investigation or review may be appropriate where facts, conduct, systems or decisions need to be assessed impartially.
- Criminal defence representation is required where a person needs legal advice or advocacy in connection with criminal allegations or proceedings.
Some matters may involve more than one potential process. However, maintaining independence and role clarity is essential. I do not undertake incompatible roles in relation to the same dispute or act in any way that would compromise an existing or proposed neutral appointment.
Who I work with
My services are relevant to a range of parties and referrers, including:
- businesses and commercial organisations;
- directors, boards and executive teams;
- in-house legal teams;
- government agencies and other institutions;
- professional services firms;
- counsel and solicitors seeking an independent arbitrator, mediator, investigator or legal opinion;
- parties involved in commercial or civil disputes; and
- individuals requiring criminal defence representation.
The appropriate engagement and appointment process depends on the service concerned, the identities of the parties and the applicable professional or procedural requirements.
Independent practice and professional experience
I have practised law since 2007. My professional background includes commercial and civil litigation, Crown prosecution, criminal trial and appellate advocacy, negotiation, dispute resolution and independent advisory work.
I hold Bachelor of Laws and Bachelor of Arts degrees from the University of Auckland. I am admitted to the High Court of New Zealand and am an Associate of the Arbitrators’ and Mediators’ Institute of New Zealand.
I practise independently from 109 Chambers and am not aligned with a law firm or dispute-resolution institution. Across my different roles, I place particular importance on:
- independence and ethical clarity;
- careful analysis of facts, evidence and law;
- procedural fairness;
- proportionality and efficient use of resources;
- clear reasoning and communication; and
- respect for everyone involved.
More information about my qualifications and professional background is available on my biography page.
Hamilton, Waikato and New Zealand-wide availability

I am available for in-person engagements in Hamilton and throughout the Waikato. Arbitration and mediation conferences or hearings may also be arranged in Auckland, Tauranga and Rotorua. Travel elsewhere may be agreed where appropriate.
Suitable arbitrations, mediations, consultations, advisory engagements and investigations can be conducted online throughout New Zealand. Online and hybrid processes may be particularly useful where parties, counsel, witnesses or decision-makers are based in different locations.
The appropriate location and format are determined by the nature of the engagement, the needs of the participants and any relevant legal or procedural requirements.
Fees and engagement arrangements
Fees depend on the service, scope of work and procedure required. Depending on the engagement, fees may be calculated on an hourly or daily basis or agreed as a fixed, staged or capped amount.
