Online retail spending rose in June buoyed by the continued growth in spending at local online sites.

Total online spending in June was 8 per cent higher compared to the previous corresponding period with spending at local online sites 14 per cent higher than a year earlier.

Spending in offshore sites has slowed with June just 1 per cent higher than the previous year.

Gary Baker, director, Institutional Research, Bank of New Zealand, said the ongoing strength in spending on food and groceries was the key driver of the differential growth rates between domestic and international online stores.

Department and electrical/electronics stores also performed well at local sites in June.

Online clothing purchases at domestic online stores were up 9 per cent on last June, more than offsetting a 4 per cent fall in spending on clothing at offshore sites.
