Kiwis have racked up more than a billion dollars in green loans for energy efficient items like EVs, solar panels, and heat pumps. 

BNZ, ASB, and ANZ all lend up to $80 thousand on a 1% interest rate over three years. 

Massey University Banking Expert Claire Matthews says these are small loans, meaning the banks are pumping them out, while not actually lending a huge amount. 

She told Mike Hosking customers still have to go through the same process as loans with higher interest rates, and go through affordability checks.
