Hayden specialises in helping government agencies and private sector organisations that work closely with government to resolve complex disputes.  He also helps clients in highly regulated sectors to comply with their obligations.

Hayden can assist you to navigate your way through the often complex process of working with the public sector and particularly to understand your rights and obligations. He has particular experience with information law issues, including working with the Privacy Act and the Official Information Act.

Hayden has advised: 

  • Heritage New Zealand on judicial review proceedings (High Court and Court of Appeal) challenging a decision to designate land as wahi tapu area, the first proceedings of its kind in New Zealand.
  • Serco Asia Pacific on all proceedings following the allegation of organised fighting at Mt. Eden Corrections Facility. The extremely high profile case held global reputational risk for Serco and wider implications for private sector businesses delivering public services in New Zealand.
  • The Medical Council of New Zealand in a disciplinary charge against a doctor who had ‘stocked’ his practice by writing prescriptions in the name of their patients. The practice was found to be negligent and had significant precedential effect.
  • The Institute of Professional Engineers (IPENZ) on its jurisdiction to hear complaints about a former member being investigated in connection to a collapsed building. The result of the case will determine the extent of jurisdiction that voluntary associations can have over former members.
  • Rachel MacGregor in a claim to the Human Rights Tribunal following a breach of confidentiality by her formal employer, Colin Craig MP, relating to a previous sexual harassment case. The process tested the efficacy and integrity of the confidential Human Rights Commission dispute resolution process.
  • The Ministry of Education in relation to a development agreement and rental obligations on land no longer required by the organisation.
