The midfielder has been linked with a move away from Camp Nou but insists he wishes to remain at the club beyond the end of his contract in 2015
The midfielder was influential as the Blaugrana ensured Gerardo Martino's first Clasico ended in victory, thanks to Neymar's first-half strike and a stunning second-half chip from Alexis Sanchez.
Speculation prior to the game had suggested Iniesta could follow goalkeeper Victor Valdes out of Camp Nou at the end of the campaign, with his current deal set to expire in 2015, but the 29-year-old has no interest in a departure.
He told reporters after the game: “I’m very happy here, and I want to stay. I’ll renew my contract soon.”
Recent clashes between Madrid and Barca have been dominated by the influence of Cristiano Ronaldo and Lionel Messi.
But with Neymar and Gareth Bale making their Clasico bows, the stage was set for two new stars to make their mark on arguably the biggest game in club football.
In the end, while Bale was withdrawn on the hour mark after a largely anonymous display, Neymar and Sanchez - who has enjoyed a new lease of life under Martino with the Catalans, stole the headlines.
"The talent players like Neymar and Alexis have is indisputable. They are players that will help Barca win titles, which is what we all want," Iniesta continued.
"We knew that Madrid are very dangerous when they’re given space, and we managed to minimise that aspect of their play, especially in the first half. In the second half we struggled a bit more."
The win sees Liga leaders Barcelona move six points clear of Madrid, who lie in third place, but second-placed Atletico Madrid could move to within a point of los Blancos with victory over Betis on Sunday night.
