"As part of our ongoing focus to transform our business, we've been reviewing how we can be faster to market, better serve our clients, align to our industry priorities and increase career opportunities for our people," said said NTT global chief executive officer Jason Goodall said.
"The changes we have decided to make position NTT as the strongest technology services company in Asia Pacific. I am also delighted to appoint Tania, who is a world-class leader and a great advocate for our clients, partners and people across ANZ."
Balcombe has worked for NTT and its predecessor companies for more than 14 years, most recently as chief marketing and go-to-market officer for NTT in Australia.
Her previous role was that of general manager of part of the Australia business.
The appointment was necessary due to the impending retirement of incumbent CEO Steve Nola, who has been with the NTT and its predecessors for a remarkable 31 years.
"I'd like to take this opportunity to once again thank Steve Nola for his extraordinary contribution to our business over the past 31 years and wish him and his family a very well-deserved retirement," said Goodall.
Nola will leave the company on 30 September 2020, and Balcombe will take up the reins the following day.
The other change Goodall alluded to is that NTT is merging the business operations of its Australia and New Zealand entities, effective 1 October.
