Substitute Issam Jemaa struck a last-gasp winner to settle the Group C contest in Tunisia's favour.
Tunisia took a fourth-minute lead through the impressive Youssef Msakni but Niger equalised four minutes later in controversial fashion when William N'Gounou netted following a possible handball from his team-mate Ouwo Moussa Maazou.
Both teams created a host of chances after that, including each hitting the woodwork, but it was Tunisia who claimed the points when Jemaa netted in the 90th minute.
The victory leaves Tunisia top of Group C with two wins from two, while Niger prop up the pool having also lost their first match to Gabon.
