Extra funding

Short answer
A second mortgage in NZ is a loan secured behind your existing first mortgage, usually from a non-bank or private lender, for 3 to 24 months. It’s used for deposits, development cost overruns, tax debt or settlement gaps. Because the lender ranks second, rates and fees are high, so it suits short-term needs with a clear exit. Your first lender usually has to agree.
