Strong investor demand saw the Government raise $2 billion from its syndicated offer of May 2031 bonds, with bids exceeding $3b.
The bonds, which carry a coupon of 1.50 per cent, were issued within the Treasury's desired range, with a yield to maturity of 1.42 per cent.
"It was well attended," said one bond market participant.
"Demand was good and it suggests that New Zealand government bonds remain attractive to investors," he said.
"They have been for a long time and that remains the case," he said.
