When the friend you've invited to Airbnb signs up and books a trip, how much they’ll get depends on the price of their reservation excluding taxes and guest fees:
Spend $400 NZD, get $20 NZD
Spend $800 NZD, get $40 NZD
Spend $1,000 NZD, get $50 NZD
Spend $1,500 NZD or more, get $75 NZD
Plus, they’ll get $15 NZD off when they book their first experience of $50 NZD or more.
