Border Force has successfully cut queuing times but other duties, like checking freight, have suffered.
Activities such as seizure of cigarettes and counterfeit goods, entry refusals and detecting forgeries, were below target.
Border Force officers put this down to staff shortages and requirements to prioritise full passenger checks while managing the queue times.
New measures were put into place for queue times as in April 2012, just before the London 2012 Olympics, staff were struggling to manage.
Margaret Hodge MP, Chair of the Committee of Public Accounts has said, "The Border Force must be able to check both goods and passengers at the same time. Border security cannot be an either or choice."
More staff are now going to be recruited to meet demands placed on Border Force.
Two people have been charged with drug trafficking offences after ten kilos of cocaine - worth up to one million pounds, was found hidden inside cakes at Gatwick Airport.
The drugs were inside baggage seized at the South Terminal on Thursday afternoon, after the arrival of a flight from Jamaica.

The two people charged are from the West Midlands - Sherelle Burke aged 22, of Bridge Street, Coseley and Kris Millwood, aged 29, of Beacon View Road, West Bromwich. They will appear at Croydon Magistrates Court later today.
"Seizures like this demonstrate how officers at Gatwick and across the country are at the forefront of the fight to keep illegal drugs and other banned substances out of the UK.
"Drug trafficking is a serious offence and those convicted face long prison sentences."
Border Force officers have seized more than two tonnes of hand rolling tobacco being smuggled into the UK through Dover on a lorry. Officers stopped an Italian-registered lorry after it arrived from Calais on a ferry on 19th January.
After questioning the Romanian driver, Border Force officers searched the lorry and found the tobacco hidden under the a cargo of cheese. Officials say the haul could have cost the Treasury about £328,000 in unpaid excise duty.
"These detections show that our Border Force officers are on constant alert, 24 hours a day, 365 days a year to keep illegal goods out of the UK. Anyone who smuggles tobacco for commercial gain is effectively stealing from the public purse and from law-abiding taxpayers. We will continue to work with HM Revenue & Customs to bring smugglers to justice."
