Muhammadu Buhari, the outgoing president of Nigeria, has pledged to address the nation's cash shortage, which is resulting in a disorderly situations as people scramble to obtain new naira notes.
The old notes can still be exchanged at the nation's central bank for a further seven days after February 10 when they lose all of their value.
President Buhari wrote, "I am aware of the cash shortages and suffering being experienced by people and companies as a result of the Naira redesign.
"I want to reassure you that we are making every effort to fix these problems. Between now and the deadline of February 10 Nigerians should anticipate major changes "He went on.
In one video, individuals were seen squabbling over cash at an ATM. Another, which we covered on Thursday, showed a man getting dressed only in his underwear while he waited at the bank.
According to the governor of the central bank, the exchange deadline was originally set for January 31 but was extended by 10 days to enable more people in rural areas to obtain the new notes.
80% of the notes in circulation, according to the bank, were not inside banks when it announced in October that the 1,000 ($2.18; £1.75), 500, and 200 naira notes would be replaced.
With the revised currency, the central bank hopes to gain a better knowledge of the flow of money across the economy and control inflation.
