He's fun to hang out with and doing so in the picturesque Pacific makes it a pleasure.
In tonight's opening episode Radar visits Rapa Nui, aka Easter Island, and investigating the island's iconic ancient statues is top of the agenda.
It's no spoiler to reveal he doesn't solve the mystery surrounding them but we do garner interesting insights, along with the nice observation from Mark, a Westie who married a local lass, that the statues were originally created to look after the island's people, a function they've fulfilled admirably by attracting hordes of tourists who wouldn't otherwise dream of coming to a place in the middle of nowhere.
Its nearest neighbour, notes Radar, "is the less than salubrious Pitcairns", 2075km away.
The ep also covers a traditional version of a triathlon - as well as feats of strength and endurance, its 22 events include paper making and dancing - and a brief history of the colonial oppression visited upon the island courtesy of Chile, touched on lightly but effectively.
Immediately after Across the Pacific is one-off Kiwi docudrama Nancy Wake: The White Mouse, about an New Zealand-born, Aussie-raised World War II hero who was considered one of the most effective leaders of the French Resistance.
Hers is an amazing story but I wasn't as taken with it as I might have been because I recently watched an ep about her in the series Kiwis at War, made by the same production company some years ago.
The feature-length docudrama inevitably traverses the same ground as the earlier piece and both feature extensive interview segments with Wake's biographer, Peter FitzSimons.
The main point of difference is the dramatised bits, with Rachael Blampied as Wake and various Kiwi actors sporting French accents.
Mercifully, no one goes the full 'Allo 'Allo and Blampied is just fine. But the earlier half-hour featured an interview with Wake herself and it's impossible to compete with the memory of the steely humour of the real deal.
Radar Across the Pacific starts tonight, 8pm, on One; Nancy Wake: The White Mouse, 8.30pm, TV One.
