According to the police, it was one of the biggest attacks by the Taliban.
Helal said that some gunbattles between the attackers and security forces continued until the morning.
Twenty two policemen also lost their lives in the clash, officials confirmed.
Police in the province said that law enforcement officers attacked the Taliban, who "destroyed the checkpoint and took away all the stored weapons". He said 45 Taliban were killed and 35 others wounded.
At least 15 policemen were wounded in the coordinated assaults.
On November 13, an Afghan official said militants attacked a police checkpoint in the western province of Farah, killing eight police officers.
"There are signs the Taliban may have used night vision technology to approach and surprise our forces, though they were spotted before reaching the posts and suffered casualties", Mehri said. "Our forces resisted until they received reinforcement and air support", said Zia Durrani, spokesman for Kandahar's police chief.
Farah governor's spokesman Nasir Mehri told Anadolu Agency police checkpoints in Pul Regi area on the outskirts of provincial capital Farah City came under attack at around 2 a.m. Monday morning (2130 GMT Sunday).
The Taliban often use bomb-laden armoured Humvees and police vehicles stolen from Afghan security forces to blast their way into security compounds.
President Donald Trump recently increased troop numbers in Afghanistan, where the United States has been at war for 16 years.
