Following its massive success in 2015, the ASB's St John toy ambulance campaign is back again to help put another ambulance on our roads.

From today block-set ambulances are available for $15 at ASB branches across New Zealand, with all money raised going towards purchasing another fully equipped ambulance for St John.

ASB head of community, sponsorship and events Mark Graham says the bank is delighted with the public reaction to last year's ASB St John toy ambulance campaign.

In 2015 ASB customers helped fund the purchase of a much needed ambulance for Canterbury, which to date, has responded to more than 1270 incidents and transported more than 780 of patients affected by these incidents to a treatment centre in the local community.

'ASB customers really got behind the cause for St John last year. In fact, one ASB customer was so inspired by the campaign he donated enough of his own money to purchase both a St John ambulance and a rapid response vehicle to service the Northern region.

'We hope New Zealanders support St John again with this year's campaign. Not only is it a great way to show support for St John, Kiwis can look forward to seeing a brand new ambulance on the road and know they played a part in making that happen.”

The ASB St John toy ambulance measures 12.7cm long by 5.5cm wide and is 7cm high, and comes in a box containing assembly instructions, stickers and 101 small parts – which are not suitable for children under three.

St John Commercial Services director Peter Loveridge says the ASB St John toy ambulances were such a sought-after Christmas gift last year and they're thrilled the campaign is running again this year.

'St John is grateful to both our partner ASB and the wider New Zealand communities for their ongoing generous support. We need more ambulances on the roads to service our communities and this campaign is a big step towards making that happen.”

The ASB St John toy ambulances will be available from ASB branches from today while stocks last.
