In the other match, Marist certainly benefited from regular Treadwell Gordon Wanganui batsman Mark Fraser having baby duties for the weekend instead of going to Masterton, as the veteran was able to spare a few hours to led his team to a 60-odd run win over St Johns Tech.
Fraser scored 101 out of Marist's team total of 167, with Tech then bowled out for around 100 in reply.
There will now be a long gap until the championship is decided as the Premier 1 T20 finals will be held on the last day of the season on March 24.
Those games will be rematches from the weekend as United will meet Marton for the title, while Tech will face Marist in the playoff for third.
The Premier 2 title was decided on Saturday and Wanganui Collegiate 1st XI claimed the championship with a 20 run win over the Wanganui Renegades in the afternoon.
In the morning playoffs, the Renegades picked up a 36 run win over Central ITM Marton Saracens 2nd XI, while the Wicket Warriors Whanganui defeated Watsons Real Estate United 2nd XI.
The other afternoon playoff saw the Wicket Warriors hang on for a nine run win over Marton Saracens 2nd XI to finish third overall.
