The agreement ensures continued gas supply for around 100 government agencies, including schools and hospitals, while providing them with security of supply and price certainty, the filing said.

Financial terms were not disclosed.

In July, the company secured up to 7 PJ of gas annually until 2032 from Greymouth Gas, per the filing.
