Welcome to the forum!
I'll offer that birds a very smart and learn how to get our attention, so whether Kiwi gets louder will depend on how you respond to her being loud. Give her attention when she's being noisy, and that reinforces the behaviour (making it more likely). You'll learn the difference between a simple flock call (wanting to keep in touch with you), and her being demanding. It will also depend on how she's kept. If she has lots to do, and is often out of her cage, it's likely she'll be less noisy than if she's bored and always in her cage. If you learn her quirks as she grows, you can also proactively learn what triggers make her noisy and avoid those.
So, it varies based on the bird's personality, but a lot depends on you
Also, I would expect some additional noise when she reaches sexual maturity and she's intermittently hormonal.
