Latics boss Uwe Rosler moved to land the 27-year-old striker in January after seeing him frozen out in South Wales.
A lack of opportunities, coupled with serious injury, have been holding Maynard back for some time, with moves to West Ham United and Cardiff bringing promotion but not a Premier League window in which to impress.
Wigan are delighted to offer a proven Football League marksman another shot at booking a ticket to the big time, with Maynard's record at Crewe Alexandra and Bristol City making for impressive reading.
He is now off the mark for the Latics, having netted in a midweek win at Sheffield Wednesday, and Rosler insists his focus at present is on getting the best out of a loan recruit, rather than looking to piece together an agreement with Cardiff.
He told the Wigan Evening Post: "It's far too early to talk about what may or may not happen in the summer.
"I said from day one that Nicky needs time, and I spoke to both him and Ole Gunnar Solskjaer about that. We were all in agreement about what we are trying to achieve with this loan spell.
"Nicky is very patient and has put in a lot of hard work on the training ground. In most cases, that has been more than anyone else because he has had to play catch-up after not playing for such a long time.
"I always said that in the end he would get his rewards, and on Tuesday night that process started.
"It will have done his confidence the world of good, and that is incredibly important.
"I cannot talk about the future, but I can say that I am enjoying working with him.
"I told the chairman when we signed him that Nicky can be a very important player for us in terms of giving us the goals we need, and he is proving me right."
