Spark New Zealand plans to invest NZ$1 billion in data centers over the next 5-7 years to meet rising demand from AI and cloud services. The company, which currently holds 25% of the market, aims to expand its capacity by 118 MW. Spark projects a 70-80% profit margin and expects a 10-15% return on investment. Despite a 54% increase in data center revenue, group net income fell 21% due to soft economic conditions.
