Yep, speaking as another kiwi, I've entered virtually everything I eat in my tracker manually. You only do each item once, and then it's available for use again. It's really quite quick and easy and you get into the habit of it.
What I did early on was, when I got home with the grocery shopping, I'd pop into the study with any item I knew I didn't already have on the tracker and add its details from the packaging then and there. That way they were available when I wanted.
You can either turn meal plans themselves off (as I did), or you can leave them on for suggestions, and then just manually enter what you did actually eat. Eg if they suggest a wheat based meal and some fruit and yoghurt after, you might manually enter a GF comparative food, and then fruit and greek yogurt for after.
