Working holiday visa. Staying full year so going over 183 days. What does becoming New Zealand tax resident mean? Is it ok?

Hi everyone once you stay over 183 days in New Zealand I understand you become a resident for tax purposes and so the tax code changes. Does it have any other implications I should be aware of? Surely this applies to most working holiday makers who stay for the full year so it’s not that big of a deal? Any thoughts on this?
