The three-day Hospitality Association of New Zealand tournament started in dry conditions at the North East Valley green on Monday, but steady rain washed out play on Tuesday.
The greens were flooded again yesterday and post-section play was shifted to the Westpac Indoor Bowls Stadium, but a power cut in South Dunedin put the stadium in semi-darkness for three hours yesterday morning.
''There is little natural light in the stadium and it was difficult to see the other end of the green,'' Monopoli said. ''We just had to adjust to the conditions.''
Because of the disruptions, the final was reduced to nine ends.
The Wakatu composite four of Murray Wigley (66), of Christchurch, Tony Cockerill (73), of Gore, Bill Johnson (69), of Waimate, and Monopoli (59), of Nelson, beat the Napier team of Alan Reid, Scott Martin, Craig Faulkner and Wayne Parker 12-11 in a tightly fought final.
''I feel pretty happy,'' Monopoli said. ''It's always nice to win an event like this.''
The team has been together at the event for the past five years and it was the fourth time that Monopoli had reached the final. Johnson won the title with the Cantabs team in 1995.
Napier led 11-8 with two ends left and had the shot on the head before Monopoli played his last bowl, which pushed the jack back for two shots.
Cockerill drew the shot on the last end and Napier gifted the extra point when it pushed a Wakatu bowl in for second shot.
Wakatu won the Bacardi Cup, which is made of Mexican silver and is insured for $37,500.
''It is the second-most valuable trophy competed for annually in New Zealand for an amateur sports event,'' organising secretary Frank Pollock said.
The Dunedin Southern men's team of Mike Bankier, Ross Munro, Bill Robertson and Charlie Burrell beat Greymouth 8-6 in the plate final.
Twenty-six fours teams competed at the annual tournament, which was also played in Dunedin in 1978 and 2002.
