Like many international tourists, the Duke and Duchess of Cambridge have included a trip to the museum in their itinerary.
But with exhibits designed by Weta’s special effects workshops, filmmaker Peter Jackson as a tour guide and no long queues, the museum’s founder is promising it won’t be a stuffy affair.
Prince William and Kate will jet over to Blenheim on Thursday to check out Sir Peter’s 21 World War I planes and memorabilia at the Omaka Aviation Heritage Centre – and director Jane Orphan has no doubt the duchess will like the experience.
Ms Orphan, who set up the museum in 2006 with her husband Graham, says dubious wives always end up enjoying the planes which are arranged with manikins and props to create memorable war scenes.
A World War II Avro Anson bomber – the only one still flying in the world – will fly overhead as the royals arrive.
The royal couple will then wander around the exhibits with Sir Peter, Prime Minister John Key, his wife Bronagh, Labour leader David Cunliffe, and his wife Karen Price-Cunliffe.
Afterwards Kate and William will get a chance to sit inside the bomber, look at other vintage warplanes, and meet the public who pop along to the open day.
Before the museum trip, Will and Kate will visit Blenheim’s Seymour Square where they’ll lay a wreath to commemorate WWI which began 100 years ago.
On Thursday evening, they’ll return to Wellington where Prince William will have one-on-one chats with Mr Key and Mr Cunliffe.
Then the duke and duchess will eat canapes with MPs and ministers at a Government House state reception where a portrait of the Queen by local artist Nick Cuthell will be unveiled.
Governor-General Jerry Mateparae and Prince William are expected to speak, a Government House spokeswoman said.
Baby George will stay in Wellington with his Spanish nanny Maria Borrallo while his parents fly to Blenheim and back.
