His Shell V-Power Ford teammate Fabian Coulthard did well to recover with 14th having started well down the grid. Fellow Kiwis Andre Heimgartner and Richie Stanaway finished 19th and 22nd respectively.
"Awesome race. I had a good battle with Jamie at the start but unfortunately he got put back," Van Gisbergen said.
"It was about staying on the track – it was very hard. There was one line and very easy to make a mistake so I just tried to behave.
"[The championship situation] could all change tomorrow – we have some work to do – the car is not perfect."
McLaughlin admitted his Shell V-Power outfit has some work to do to fight the Red Bull cars on Sunday.
"We have got plenty of work to do but at the end of the day it was step in the right direction," McLaughlin said of his race pace.
"We just need another big chunk again. We will move on and work as a team and just get through it."
A longer race awaits drivers on Sunday.
