Recommandation for bus from Uni Waikato to Airport?

Hi:

I am a student and will visit Uni Waikato late this month from Australia.

I searched on Google Maps, noticing a bus line 24 from Hamilton Central to a place near the airport, then walked for 2.6 km, I am wondering if anyone has tried this route? Also, if I pay for a taxi/uber from the city centre/uni to the airport, how much would it be?
