The birdies were flying at Kingston Heath Golf Club today as Team New Zealand rocketed up the World Cup of Golf leaderboard.

Danny Lee and Ryan Fox combined to reel off 10 birdies, counteracted by two bogeys to post 8-under 64 in the second round.

They are now tied 5th alongside their playing partners Joost Luiten and Darius Van Driel from the Netherlands who also fired a 64 to be 5-under the card for two rounds.

"We always thought this would kind of be our format.  We played really nicely today," said Fox.

"Danny hit some great iron shots the whole way through the round, holed a couple of nice putts and I managed to play the par-5s pretty well today so we combined pretty well as a team."

"Joost looked like he was going to hole everything he looked at.  It was just a fun day all around."

The low scoring day was made even more poignant with the New Zealanders pledging to donate NZ$500 to the Kaikoura earthquake fund for each birdie. So far they have raised NZ$6,500 with 10 birdies today and three yesterday.

After a successful day in the fourball format, Lee and Fox are looking forward to trying their hand at the foursomes format again tomorrow.

"We will play a little more conservatively tomorrow.  As we saw, scoring was pretty tough yesterday," added Fox. 

"Anything around par is a pretty good score, and if we can get the putts to go in like we did today, we can definitely shoot 2 or 3-under easily."

Fox and Lee are hoping to win New Zealand's first World Cup of Golf title after the country has recorded two runner-up results. 

"Obviously we'd love to get our names on the trophy.  I don't think there's been a New Zealand pair win it," added Fox, with a cheeky little comment alluding to the rivalry between Australia and New Zealand as sporting nations.

"It's always nice to get one up over on you guys, especially on home soil, I'll leave it at that."
