Following the departure of Simon Butt, incumbent Director & General Manager Mark Bauer has now been appointed Manteena Group CEO. On Monday 23 August, it was announced that Simon was stepping aside from his daily role of Chief Executive Officer, shareholder, and director of the companies making up the Manteena Group. Mark will focus on the executive management across Manteena’s three main business streams: commercial, security and residential—whilst still maintaining a strategic operational role for all commercial works.
“Although the industry is facing significant challenges during the pandemic, Manteena is well positioned both financially and at an operational level with its capability and capacity to ride out this wave,” Mark said.
“We are looking ahead to the construction industry rebounding from the current pandemic situation and I’m really excited to expand my role and lead the Manteena Group into the next phase of its development”.
Mark is a director of Manteena – a position he’s held since 2000. In 2004, he was given responsibility for the general management of all Canberra activities as Canberra Branch Manager, in response to the strategic expansion of the company to include business operations in other regions. Mark officially became General Manager in 2008 and now succeeds Simon Butt in the role of Chief Executive Officer.
Manteena Group CEO Simon Butt has announced that he is stepping aside from his daily role of Chief Executive Officer, shareholder, and director of the companies making up the Manteena Group, effective 13 August 2021.
Simon started with Manteena in 1989, when company founder John Hailey employed him as a Project Manager. In 1994, Simon was invited into the business as a shareholder and upon John’s retirement, he then assumed the role of CEO to lead the company through a period of significant growth and expansion. In a career spanning 42 years, Simon has made a significant contribution to Manteena and the construction industry, particularly in the role of National President of the Master Builders Australia (2019-current).
Simon has had the fortune of working on and being associated with projects at many of the iconic national institutions, which make Canberra such a special place: National Gallery of Australia, National Library of Australia, Old Parliament House, Parliament House, Australian War Memorial and Anzac Parade.
The team at Manteena, both past and present, wish to extend their best wishes to Simon in his future endeavours and thank him for his outstanding contribution to the company.

Congratulations to our CEO, Simon Butt, who was elected President of the Master Builders Australia!

This is the second time in its 129 year history that a Canberran will lead the peak building and construction body—the only national voice representing all sectors of the industry.

We know first-hand of Simon’s passion for building & construction therefore the MBA will benefit immensely from his experience and leadership.
