United defenders Sarah Graham and Becca Peach worked hard to keep Campion at bay, but Tayla Broughton found a way through.
She cut in from the right and her shot from 10 metres seemed to deceive United goal keeper Mel Knight.
Although United spent much of the first half defending, they tried to make the most of any opportunities they had.
Claire Bayliss, Kim-Maree Larby and Amelia Paull worked tirelessly in the midfield and set up chances for Tessa McDonald and Chelsea Simpson.
United's efforts were rewarded just before halftime, whenPaare Ahuriri-Leach scored after following up on a cross from McDonald.
Referee Kieran Grealish, who had a great game, blew the whistle for halftime with Campion 2-1 up.
United took advantage of the wind behind them and put plenty of pressure on the Campion goal, where keeper Kat Vanderbilt had her best game of the season.
United hit the post on one of many raids and came close several times.
Campion steadied the ship and central defender Maggie Preston made several telling intercepts.
Campion's third goal came from a Dara Mulrooney inswinging corner to the far post, where Lucy Allen rose to head home from six metres.
Miah Sommerton had a strong game on the right flank for Campion.
Both teams competed for everything and played the game in good spirit.
Tatapouri Marist Thistle and Gisborne Girls' High School fought out a 1-1 draw at the Rectory.
Both goals came in the first half of a tightly contested game that had numerous scoring opportunities for both teams.
Amy O'Rourke was the Marist Thistle goalscorer and Gayb Kirkpatrick was their player of the match . . . she had a strong game at the back and put a stop to many attacks down the wing.
Tracy Harkess continues to improve every game. She and Danni Hunter had strong games in midfield for Marist.
Steph Collier scored the Girls' High goal — a great finish, according to coach Lee Smith.
“We battered them but couldn't get the ball in the net,” Smith said.
“Mandy (Owen) had a good game in goal, but we missed more than she saved.”
Gisborne Laundry Services Wainui Riverina coach Lizzie Hall praised the play of Bohemians goalkeeper Cassidy Beauchamp.
She said it was Beauchamp who kept Wainui scoreless for the first 20 minutes. She got to everything and made some unbelievable saves.
Wainui striker Larisa Allan added two goals to her impressive tally for the season.
Wingback Tori Burt hit a 20-metre shot that held up in the wind and dropped just under the crossbar.
Burt, along with the Wainui backline, supported play well.
The midfield ran hard and created some good opportunities for the strikers. The final score of a “fun game” was 3-0 to Wainui Riverina.
Bohemians coach Graham Maclean said he was proud of the way the Bohemians women bounced back from their early-season loss to Riverina.
He felt 3-0 was probably a fair reflection of the game but Bohemians showed great heart throughout.
Maclean said his team had many standout performances in this game but he wanted to make special mention of keeper Beauchamp, defender Teah Te Omanga Kahaki and midfielder Fern Jones.
Wainui Riverina have 16 points from five wins and a draw. Campion have 15 points from five wins and a loss . . . to Wainui Riverina.
These teams were to meet again tomorrow but the game has been postponed.
It looks like it will be a match worth the wait.
