Apple temporarily stopped Google from offering its employees internal-only iPhone apps.
The tech giant has took the decision after Google broke its developers' policy, having previously taken the same action against Facebook.
Apple subsequently restored Google's access to the software, while Facebook has also now had its access to the apps restored.
A spokeswoman told the BBC: "We are in the process of getting our internal apps up and running. To be clear, this didn't have an impact on our consumer-facing services."
Apple allows a number of firms - including Google and Facebook - to have additional control over employee devices in a bid to provide extra security.
Meanwhile, in December, Google announced plans to build a $1 billion campus in New York's West Village.
The tech giant is increasing its presence in the Big Apple by employing 7,000 more people, thereby doubling in size.
Ruth Porat, Google's Chief Financial Officer, said in a statement: "New York City continues to be a great source of diverse, world-class talent. That's what brought Google to the city in 2000, and that's what keeps us here."
