The side, which struggled to register their first points, were on target after overcoming Matavera in the battle at the bottom at home on Saturday.
After winning the toss, Nikao wicket keeper and manager Helena Tiare elected to bat, sending Matavera to field in the sweltering sun.
The host managed 168 runs for the loss of eight wickets and in reply, the winless Matavera were all out for 126, handing Nikao a 42-run win.
Tiare said the win was welcome news for the team, which is using the competition as a social event.
“We are a small team of mothers who play cricket for fun. This is our first win of the season and we hope this will boost us to get more wins in the competition.
“Last year, we were targeting to win three matches, so we could have got some sponsorship but just managed to win one. “We have managed to get some support from our families in Australia and New Zealand but we’re still targeting at least three wins this season.”
In the other women’s matches, Tupapa also recorded their opening win after overcoming
Arorangi Red Hot Chicks, while Muri overcame TKV at the Happy Valley.
In the men’s competition, Apii Mamanu’s half century was not enough for the Arorangi Red Back as the side went down to Rehab Titans who timed their run chase to perfectio,n winning in the last over.
