Is my Kakariki comfortable with being touched?

We brought a female Kakariki about 6 weeks ago and in the past week or so, she's really settled and is now very tame! She steps up, kisses your hand and sits comfortable on your shoulder! Today, I tried stroking her, and she didn't fly or even move away from me, instead she dropped her wings ever so slightly and started making a nattering noise; a noise she sometimes makes when she sits on your hand.

However, when she's stroked, this noise is a lot louder. Is this an affectionate noise or a warning? I'm not too sure, as she shows no signs of aggressiveness or obvious signs of discomfort.
