The last surviving Dambuster pilot presented his war medals to Motat this morning in a ceremony attended by the benefactor who brought the medals to New Zealand, Lord Ashcroft, and Prime Minister John Key.

Tauranga's Les Munro put the medals and logbook up for sale to raise money for the ongoing upkeep of the Bomber Command memorial at Green Park in London.

Lord Ashcroft, who also donated substantially towards the memorial construction, offered to donate $150,000 towards the memorial's ongoing upkeep, and Les accepted the offer.

The medals and logbook were handed to Lord Ashcroft at the Bomber Command Memorial last month. He then flew with them to New Zealand to personally deliver them to Les, so he could in turn hand them to Motat chief executive Michael Frawley.

Les, aged 95, was awarded the French Legion of Honour at a ceremony in Auckland this week with seven other Kiwi veterans.

They were presented by the French ambassador, Florence Jeanblanc-Risler, in recognition of their bravery in defending France during World War II.

When asked by 3News this week if the Legion of Honour would join the other medals at Motat, Les said he didn't know.

'I've only known this for a week,” he explained, 'so I'm not quite sure where I'm going to wear it, so it may well end up with the others."

This morning's presentation took place in front of one of the few remaining examples of the Avro Lancaster Bomber, which was made famous as a successful night bomber by the RAF Bomber Command in World War II.

'It's our intention to develop an exhibition highlighting what Mr Les Munro, Mr Len Chambers and the other New Zealand members of Bomber Command, in particular 617 Squadron, did during the war," says Motat CEO Michael Frawley.
