National Australia Bank and also ANZ are picking up some market share in home loans, the monthly banking statistics from APRA show.NAB increased its home loan book in Australia by 1.2 per cent over one month and by 4.1 per cent over three months. ANZ increased its book by 1.1 per cent and 3.6 per cent over one and three months respectively.Bendigo and Adelaide Bank also reported growth of 1.1 per cent for August, a possible marker of an improvement in its business levels now that the group is lending more aggressively through mortgage managers once again.Westpac's market share, while growing, is below that of all banks, with growth over one month of 0.5 per cent and over three months of 1.8 per cent, so the bank's higher pricing might, finally, be having a minor affect on volumes.
