The second chase began around 10 minutes later when a vehicle with three occupants fled police. The vehicle crashed on State Highway 5 near Ngongotaha moments later.
Judge MacKenzie said in court it was possible the teenagers would each face additional charges when police finished their investigation.
The chases come as new figures show the number of drivers fleeing police in Rotorua is on the rise.
According to the figures, provided by police, 87 drivers fled in 2015, an increase from 58 in 2010. There were 73 drivers who failed to stop for police between January and September last year.
Figures for October to December were not available.
Officer in charge of road policing Senior Sergeant Nicky Riordan said she would not comment on the figures or reasons for the increase.
Instead she wanted to stress the risks of failing to stop for police.
"The risk is too great for one moment of poor judgement. It is vital when a driver is signalled to stop, they do so.
"A lot of the time the reasons people don't stop is for things like not having the right licence class. In the end, the consequences would be far less that if a chase ensues.
"Nothing could be as bad as killing yourself or somebody else. When a driver fails to stop or drives outside their capabilities there is a risk not only to their life and the lives of their passengers but also the lives of every other road user. It's just not worth it."
Ms Riordan said she could not say how many chases ended in crashes or the reasons people fled police.
