You said you got it from online so i did a quick search for matching images and the photo comes from Trees South africa (the watermark that is partly cropped out in your image says this to) according to their website it is Harpephyllum caffrum.
Higher resolution image is on this sight which further back up it being Harpephyllum caffrum (leaf shape and arrangement match) def not karaka as karaka leaves are shaped differently.

It seems that’s the one indeed.
