Kenny Mutton continued his love affair with the Wairoa River this weekend while fellow Okere Falls paddler Louise Urwin finally shed a run of bad luck at one of New Zealand's most prestigious extreme kayaking events.

The pair took home the men's and women's titles respectively at the 2013 Wairoa Extreme, held near Tauranga on a stretch of river embracing the grade five "Waterfall" and "Rollercoaster" rapids.

For Mutton, it was a continuation of his ageless form in the event, which he first won in 2002. He also won in 2008 and today's title left him in exalted company as one of only two men - with Donald Johnstone - to have won the race three times.

The 41-year-old beat Rotorua-based Canadian Tyler Fox in a dramatic final, which saw Fox forced left on the first drop and take several seconds to right himself.

"I wondered about paddling back and getting him out of the Waterfall so we could start the race again but then he popped out so I carried on," Mutton explained.

"I wasn't thinking straight going into the next section and ended up getting stuck in there but luckily so did he. Luck definitely plays a big part in this race and I had it with me today."

Mutton, a former international class freestyle and rodeo paddler, headed defending champion Jamie Sutton in the semi-final, with Sutton looking to win three titles in a row. Fox had earlier squeezed past John Snook, who won the inaugural Wairoa Extreme title in 1998, in the other semi-final.

Urwin, meanwhile, had to get a monkey off her back before claiming the title, edging Auckland's three-time winner Toni George in the women's final.

"I've got quite a few second-placings going back eight years or something" the 32-year-old said.

"Last time I made the final (in 2011) was also against Toni and I was winning, then she just got me at the bottom. It was nice to get one back on her but to be honest anyone could've taken it today because the girls coming through in New Zealand are some of the best racers in the world.

'There's such a high level of paddling, because they're always paddling together and pushing each other."

Urwin spent the end of 2012 chasing massive water in Chile at the Whitewater Grand Prix and hasn't lost her edge over summer in Rotorua.

"I feel like I've been fitter but I'm paddling really strongly. I was in pretty good shape going into Chile and I've done a lot of stuff in the last year so I'm feeling pretty good."

Urwin earlier beat Kim Dodd in her semi-final, while George slipped past double Olympic slalom representative Luuka Jones in the other semi-final.

The race is part of the New Zealand Extreme Race series, which also features next month's Citroen Extreme Race on February 23 in Queenstown, followed by the Bullerfest BoaterX held on March 1 in Murchison.
