Big rigs are set to invade ASB Baypark this weekend in an effort to raise funds to help make children's stays at Tauranga Hospital a little less distracting.

The shiny rigs and impressive light displays from 49 trucks will be on display at the inaugural Baypark Truck Display this Saturday.

Mainfreight trucks will be among the 60 trucks taking part in the display on Saturday.

All proceeds will be donated to Tauranga Hospital for the care of children – some used to create a children's distraction wall in the Emergency Department.

Event organiser Alex Salter, of Salters Cartage Limited, says support for the event has been overwhelming after what started out as a small 15 truck event.

It has since tripled in size and popularity with 60 trucks registered for Saturday's convoy and the 49 for the show later that evening, which will coincide with ASB Baypark's Super Stock Dash for Cash.

The trucks are convoying from the Tauriko Business Park at 2.30pm tomorrow along the toll road, expressway, down Hewletts Road, along Maunganui Road and then into the stadium.

'There's 49 registered for the show, but we have had so much interest that I have said anyone else that wants to do the convoy can, but they can't do the show,” says Alex.

'We have trucks from Hamilton, Auckland, Tauranga, Opotiki, Taupo, Te Puke and Whakatane. One is based in Taupo and he's in Cromwell at the moment and is coming back for it.”

The idea for the show emerged from the countless hours Alex spent as a four-year-old at the Tauranga Hospital while her mother recovered from a speedway accident.

The 26-year-old's mother Natalie spent three months at the hospital recovering and during that time she was adopted by the staff of the Children's Ward.

Then in 2013, while at Baypark Speedway, her 16-month-old nephew Kodi came down with a fever and was cared for at Tauranga's ED.

Alex says one of the hardest things was keeping Kodi distracted while he was being treated, so the idea of helping to fund a distraction wall is particularly appropriate.

'The hardest thing to do is try and entertain a kid with a fever who is in a world of pain.”

Alex, along with 30 of the big trucks, will be visiting Tauranga Hospital's Clarke Street carpark on Saturday from 1pm to 1.30pm and will be greeted by Emergency Department staff.

Emergency Department clinical lead Derek Sage thanks Alex and her fundraising companions for the heart-warming generosity saying it will greatly improve both children and families' experiences.

'Children coming into the ED are either ill or injured and they can be scared because it's an alien environment to them. If we're able to distract them it means making a good initial assessment is that much easier,” says Derek.

'Additionally, the child might have to undergo a painful procedure and we have found in the past that, when good distraction is employed, they hardly even notice.”

Other items currently used to distract youngsters attending ED include toys and blowing bubbles.

'Generally anything that is interactive and busy tends to work well. The distraction wall would be a very welcome addition to the methods we already employ.”
