Both of the leading pair birdied the long sixth, and Lara almost holed-in-one at the par three eighth, leaving a tap-in birdie.
It came after his first bogey of the day at the seventh, however, and so both players were tied on 13 under, with Campillo only one behind after a fifth birdie of the day at the tenth.
Kruger holed a birdie putt from 20 feet at the eighth and at 14 under entered the back nine with a one shot lead.
A fourth birdie of the day followed for Kruger at the par three 11th, and with Lara beginning to struggle from the tee the former amateur star moved three clear.
That was because 34 year old Lara scrambled pars at the ninth, tenth and 12th, but caught a flyer on the 13th and his 25 foot par putt finished a fraction short.
