Online spending at overseas sites has continued to grow strongly and was last month up 14 per cent on the same time last year according to new figures.
However, the value of online spending domestically was only up a mere 2 per cent on last January, according to BNZ's latest quarterly online retail sales report.
The report also showed New Zealanders' total online spending last month was up 7 per cent on the same time in January 2014.
Online retail sales last month were typical of the trend over the last 12 months - up 8 per cent for both the three-months ending January 2015 and for the year ending January 2015 on the prior corresponding period.
The seasonal post-Christmas drop in spending was in line with previous years, dropping between 18 and 22 per cent between the months of December and January, the report showed.
