Litigation / Restructuring and Insolvency

DDI:+64 9 300 7611


Michael joined Martelli McKegg in 2023. He has over 15 years' experience litigating complex financial disputes, both in New Zealand and the United Kingdom.

Michael started his career at a top tier New Zealand commercial law firm, before spending three years at the London office of a US litigation firm. He has particular expertise in M&A/investment disputes, restructuring-related matters, civil fraud and 'soft IP'.  His experience extends across a range of industries, but in particular Property, Private Equity and Banking/Financial Services.

In his most recent roles, Michael worked on fixed contracts for specific complex disputes (in London, assisting on various matters for the former CEO of a collapsed private equity firm; and, on returning to New Zealand, defending an IT services provider from a damages claim in relation to a complex ERP project).

Michael has been instructed on cases at all levels of the New Zealand Courts, the English High Court, various offshore jurisdictions (Cayman Islands, BVI and Curacao, in a supervisory role) and in domestic and international arbitration (ICC, LCIA and ad hoc).  He has appeared as counsel in the New Zealand District and High Courts and Court of Appeal and in international arbitration.

While Michael enjoys advocacy, he does his best to keep his clients out of Court.  His experience in this respect includes acting on internal investigations, due diligence exercises, risk analysis and contract negotiations.
