President Uhuru Kenyatta on Tuesday directed the Kenya Revenue Authority to allow the Shimoni port in Kwale County to operate around the clock.
The President issued the order following complaints from locals.
"We want this to be a major fishing port apart from just bringing in goods," he said.
Locals had complained that they were unable to effectively trade on the Kenya-Tanzania border due to time constraints.
President Kenyatta, who is campaigning in Kwale along with his Deputy William Ruto, also asked residents in Lunga Lunga to support and vote for Jubilee in the August 8 elections.
"This time we should walk together to end poverty and create jobs for youth," he said.
He said his administration has built roads, increased electricity connectivity and water supply and also issued land title deeds to locals.
He said more than 40,000 title deeds had been issued to residents in the county.
He said the Jubilee government was keen on implementing free secondary education from January next year.
"The work of parents now is to deliver and take care of the child," he said.
Mr Ruto said the Jubilee administration has built more roads in Kwale than any other government.
He urged locals to choose between a government that delivers and one that thrives on propaganda.
President Kenyatta also issued title deeds to residents.
Kwale Governor Salim Mvurya urged residents to vote for President Kenyatta in the August polls.
