Mike Davies ATAINZ

Mike Davies

Board Member

I joined ATAINZ in 2008 and have attended all of their annual conferences since then except one. Strategic planning has always been a task that I have enjoyed and with ATAINZ looking to set a new Strategic direction I felt that I was in my element and agreed to stand for the Board. As an Institute I believe ATAINZ has come out of its shell and is now forthright in representing industry issues across a broad spectrum of government and industry players. We are now getting the recognition we need as a representative body to help shape industry and tax for the future. We are now a “voice” for small business.
