The 16,000 square foot (1485 square metre) data centre will be part of a 56,000 square foot (5200 square metre) facility built in collaboration with Highbrook Development.
"This is a highly significant investment in New Zealand's future technological infrastructure," said Jennifer Moxon, managing director of IBM New Zealand.
"It is the result of long term strategic planning and signals IBM's commitment to enable New Zealand to become a world class technology centre and advances the growth of the digital economy," she added.
In particular, IBM intends to deliver cloud computing to its New Zealand customers from the centre.
The data centre is being built with energy efficiency in mind. For example, the cooling system will draw cold air from outside (according to season), reducing the need for chillers.
The design also allows for future expansion as demand rises. IBM expects to invest more than $NZ80 million in the centre over 10 years.
In related news, IBM has opened a cloud computing laboratory in Hong Kong. It will serve as a development facility for Web 2.0, cloud mail and collaboration for businesses of all sizes.
This is IBM's tenth cloud computing lab, and part of its brief is to identify and drive best practices for its cloud messaging business in critical areas such as security, privacy and stability.
"The opening of the laboratory demonstrates Hong Kong's advantages as a global hub for world-class information technology and online services and we are delighted that it aligns with the government's agenda of developing Hong Kong into a centre of excellence in innovation and technology," said Dominic Tong, general manager, IBM China/Hong Kong.
