Labour says general practices using its low-interest loans, should be able to repay them within 10 years

The Family Doctor Loan Scheme would offer up to 50 loans a year to help doctors and nurse practitioners set-up or buy into practices.

If fully subscribed, it would lend out 25-million-dollars a year.

Health Spokesperson Ayesha Verrall says the 7.5-million-dollar capital cost would be funded by revenue from Labour's planned Capital Gains Tax.

She says if owners can't pay the cost back in 10 years, they'll need to set up a payment plan with IRD - but believes that's unlikely.
