Kuyt was pleased with the result and performance and has called for more of the same in Saturday's away game against Portsmouth.
"It's a really important win. We showed we wanted to win and played good football for most of the game," the Dutchman told Liverpool's official website.
"Maybe we could have scored a few more goals, and we are disappointed to have conceded, but the most important thing is winning and that's what we did.
"A victory will always lift confidence, but we live from game to game now and we just needed to make sure we beat Wigan.
"We can enjoy this result, and then we have to do the same again on Saturday and try to start a winning run of form."
Kuyt admits Liverpool cannot afford to look too far ahead as they strive to climb the table from their current position of sixth.
"We just wanted to win against Wigan and then take it from there," he explained.
"The situation for us now is to look from game to game, so we are very happy to have got the three points and now we can't wait to play again this weekend.
"For us, every game is very important, so in that respect nothing has changed, but we need a couple of victories and we definitely want another three points against Portsmouth."
