There are some good points here (asking for feedback, self examination), and i'll happily confess to not knowing much about the subtleties of employer-employee relationships in NZ.
But there are also some missteps.
I did not recommend brandishing your accomplishments. I do recommend knowing what they are and being able to prove them though. Knowledge of self is never a bad thing.
This whole spiel also isn't about individual managers. When i refer to the employer-employee relationship, the employer side isn't one person (usually), it's a process, structure, system. So it's possible for you to be the best manager (smart, compassionate, aware of your subordinate's contributions) and for the system to still suck e.g. too few promotions/raises to go around, manager has to sell his boss on you etc. etc.
Here's the rub. We are all responsible for our careers. You, me, all of us. It is always the individual's responsibility to champion himself/herself (all external support is of course welcome). Telling employees to work hard and leave the "championship" to their managers seems rather naive to me (and a little paternal).
Great careers don't just happen. Your manager isn't (always, or even frequently) going to bestow one upon you after noticing all the good things you do.
It's all you.
