"We would have won it, that's how close it was," said coach Chris Waterson.
"It was just a magnificent display, it's just a shame we couldn't win."
It was also the first time in a number of years that Wanganui have beaten Wellington at the hexagonal.
Waterson then settled on the seven players from this squad of 10 who will attend the NZ Intercentre championships, being held in Christchurch on March 28-29.
Dianne Paterson will be the single, the pair is Lesley Bourke and Anne Loveridge (s), while Pam Burgess moves from pairs to the fours with Marlene Foster, Pauline Pirere, and Marilyn Constantine (s).
"We're bullish about our chances of making the top eight this year," Waterson said.
The Wanganui men, without some of the district's leading players, averaged two and a half games per round, with two draws and two games lost by a point.
"The players were all out there giving their best and, as always in bowls, you need the rub of the green which we did not seem to get too much of," said manager Mike Morgan.
"However we are satisfied that the outcome finishing equal [3rd-4th] was a good effort."
Singles player Clint Pair and the pairs team of Ian Porteous and Tony Waikato had the most success with three wins and a draw each from their games.
