Spark New Zealand's (NZE:SPK, ASX:SPK) wholly owned subsidiary Spark Finance has completed a refinancing of its bank debt, establishing a new NZ$500 million committed facility to replace existing arrangements, according to a Friday New Zealand and Australian bourse filing.

The facility will support general corporate funding needs following the sale of a 75% stake in its data center business in January, per the filing.

The revised structure extends maturities to up to five years and preserves existing lender and bondholder undertakings along with the negative pledge provisions, the filing said.

The company said the refinancing does not affect its fiscal 2026 guidance or its capital management framework, the filling added.

The company's Kiwi shares were down 1% in recent Friday trade.
