He says it gets worse with alcohol consumption. Obviously, in England, there's something in the beer that affects their ears.
But we go through the usual rigmarole where I rattle off Maori place names and he falls about laughing. Whakatane and Whakarewarewa are firm favourites when pronounced correctly (if you get my drift), especially in London where babies say the "eff" word before they can walk.
Anyway.
A day later a family wedding is all wrapped up, and cousin and I find ourselves winding down in a small pub in a delightful English village and he's just told the friendly locals I'm a Kiwi.
As expected, sheep noises come floating across the room.
But now a local has approached to sniff the Kiwi. I introduce myself. "Kevin" I say, as we shake hands.
His look confirms he's struggling with my accent - "Kivin?" Odd name - and quick as a flash cousin sees an opportunity to improve our "liquid assets", which are by now barely covering the bottom of the glass.
"Tell him that place name you told me," he says, nodding towards the still vexed local.
"Whakarewarewa," I say, emphasising the "f".
The local roars with laughter so I throw in "Whakatane" (similarly emphasised) just for good measure. We've made a friend and as he heads off to the bar to buy us a drink, cousin smiles knowingly. A real Londoner never misses an opportunity.
And it doesn't stop there.
As word spreads around the bar other locals are keen for a taste of New Zild and with cousin taking the appearance fee, the drinks add up as I find myself discussing all manner of things. To be honest, I did lay it on a bit thick.
The locals particularly liked the story about finding "tin sints in the kaa paark at Fukatarney after daark" but we realised it was time to go when stunned silence met my reply to a question about what I was going to do when I got back to New Zealand.
"I'm going to paint my deck," I said.
