Spark New Zealand (NZE:SPK, ASX:SPK) said Tuesday that Port Nelson has deployed a private 5G network in partnership with Spark and Ericsson Enterprise Wireless Solutions, covering about 30,000 square meters across three warehouses in Nelson and Blenheim.

The company said in a statement that its 5G+ Private Network solution uses Ericsson Private 5G to provide a high-availability core at Port Nelson that connects to small cell radios, delivering reliable coverage inside the warehouses and across outdoor yard areas.

"Port Nelson is a great example of how private 5G is unlocking new value for New Zealand businesses operating in complex, production‑critical environments," said Greg Clark, chief customer officer at Spark.

Spark's Australian shares and New Zealand shares both rose almost 1% in recent Tuesday trade.
