Mark Lash

Tax Partner - Wellington



I am passionate about helping my clients realise their potential on a domestic and global stage, ensuring that tax is not an impediment to realising their aspirations. While my main focus areas are working with our private clients and with iwi to create value for the long term, I also work with a number of larger corporate organisations, meaning I can draw on those experiences to add value. 

I have the privilege of working with some of the fastest growing and most successful organisations in New Zealand. This may be as a client or through my role as the Wellington and Lower North Island regional leader of the Deloitte Fast 50 programme.  I believe that business is based on personal relationships and many of my professional relationships have developed into long term friendships.

Iwi affiliations include:

  •            Ngai Tahu

Mark’s areas of expertise include: 

  •            Private client services
  •            Maori business tax and advisory
  •            Business tax
  •            Tax structuring
  •            International tax
  •            Mergers & Acquisitions
