Hurricanes captain Dane Coles lauded the quality of New Zealand Super Rugby teams, comparing derbies to Test matches.
The All Blacks hooker said before his side's clash with the Blues on Saturday although he enjoys the games they are incredibly challenging.
"I love playing New Zealand teams but the New Zealand derbies – not being biased – but they're bloody tough. Some other teams don't even play New Zealand teams so, personally, I love playing them, but once would be enough," Coles told Stuff.
"They're like test matches. Like, you know, the New Zealand teams want to go out and kill each other. You've got to prepare very, very well against New Zealand sides, if you're five per cent off you could lose to anyone."
Coles also made a valid point about the international rugby calendar and how it correlates with the Super Rugby schedule as the players had a one day turn around from finishing with All Blacks proceedings on Sunday and then having to head to their Super Rugby teams on Monday.
"It was bruising, I played some big minutes (during the three Test Series against Wales) and to be honest (Hurricanes practice) on Tuesday I was probably a bit flat. But I had the day off yesterday and was fresh today, but I'll keep chipping away," said Coles.
