The Defence Force has alerted potential bidders that it is in the market for new communications systems.
The project, called The Network Enabled Army, is in a pre-acquisition phase until it gains Cabinet approval.
The first tranche of the programme is estimated to cost a $106 million and will run for up to four years.
A spokesperson said the programme was needed to modernise Defence Force communications systems and other systems used for command and control of the New Zealand Army.
She said the programme will improve situational awareness, reduce the risk to frontline troops, improve the operational effectiveness of Army Units, and ensure the Army can continue operating in coalition forces.
"It will enable the ability of Army units to communicate with the aircraft and ships of the Royal New Zealand Air Force and Royal New Zealand Navy."
