As a British speaker I would expect:
Nobody needs to hurry, do they?
However, and in response to your comment, we could also say
Nobody need hurry, need they?
The second option sounds strange but is also correct (in my opinion).
My understanding is that if you use need
'need' and to
'to' you are using need as a main verb, not as a semi-modal verb. (Source: https://dictionary.cambridge.org/grammar/british-grammar/need)
