There's surprise the Reserve Bank is looking to crack down on low deposit lending

The bank wants to halve the number of people borrowing more than 80 percent of the property's value, by cutting the number to ten percent.

It could be in place from October.

Independent economist, Tony Alexander, says he doesn't think the increase in low deposit lending is all that worrying.

He says it was still only 9.6 percent of housing lending, so already below the 10 percent limit.

Alexander thinks it may be due to the trend which has been going up, especially among first home buyers, over the past three or four months.
