Australian Matthew Griffin has claimed the BMW ISPS HANDA New Zealand Open with a clutch birdie on the final hole of the tournament.

Starting the day two shots behind Japans Hideto Tanihara, Griffin opened his final round by eagling the first.

Finishing tied for third and six shots off the lead was leading New Zealander Michael Hendry and Japans Shunsuke Sonoda.

Yoshinori Fujimoto (JPN) finished outright 5th on 13-under 274 with Steven Alker (NZL) a further shot back.

Rounding out the top-10 on 11-under the card are Australians Deyen Lawson, Todd Sinnott, Matthew Giles and Rory Bourke.

For his win today Griffin picks up NZ$180,000 which provides him with the top billing on the PGA Tour of Australasia Order of Merit.

"I just hit driver and hit it hard down the right. I thought I hit it on the perfect line, it gave a right kick and it must have snuck down. In the end I had the perfect yardage; I hit a wedge to a nice close range, long enough to still miss, so it was nice to roll it in. With Tanihara it was a bit unfortunate as his drive just rolled over and went into the rough."

"It was the most nervous Ive been, I did a lot of deep breathing on the green and it was a nice putt."

"Youre always nervous on the first tee, I hit a couple of shots in close and it really settled the nerves."

"I took on 16 and 17 as I knew I was behind and hit good spots but came up with pars - the last was a great way to finish."

"My girlfriend Liz, family and friends are here, the celebrations are going to be pretty big. Its the first time that my parents have travelled overseas to see me play and its the biggest amount of people Ive had at any event and there will be a drink out of that trophy before the night is over!"

"This is by far the biggest event Ive won. To win the New Zealand Open, its got so many good names on the trophy, its a real step forward for me."

Hideto Tanihara, 69, 66, 63, 70, 19-under 268, runner-up

"When it went in the bunker I thought it would be ok. I wasnt particularly worried and it wasnt a shock."

"However, the last putt I had I thought it was going to go in and I just came up a bit too short, which was a shame."

"Thats the way that golf goes, there are many good players here out of 144 only one can win. I would like to try the same challenge again in the future."
