Australia have the same problem - their Sheffield Shield is put on ice until 12 days after their fourth and final test against India, while the hugely over-hyped Big Bash T20 starts on Friday.
Wright knows it's far from ideal.
"I think it's a huge issue," he said.
"That's a real complication in the development of test batting, make no mistake about it.
"Everything's got its place, but particularly for young players you're almost telling them one message, for test matches, then with T20 it's another.
"It's a big challenge but it's part of the environment."
Wright took a pragmatic view of the cliffhanger seven-run win over Australia at Bellerive Oval on Monday.
One victory doesn't mean everything is rosy again in New Zealand's test garden.
"I know we've got competitive T20 and ODI sides, which we showed at the World Cup [last March]," Wright said.
"But I know we've got a long way to go if we want to be a consistently winning test side.
"We've had a great win, but we've still got South Africa coming. They're a tough side but, hopefully, we just learn and get better."
Wright pointed out that more of value and insight into players can be gleaned from wins than losses.
"There are certain things that have come out of the series where you learn a little more as a coach.
"Our test team is going to take some time to be a really good test team, but these are little milestones that will help us on that development."
He reiterated his recipe for successful test cricket. "Really it's a discipline and ability to play for long periods of time for five days.
"We stuck to the basics [on Monday], that's the big thing.
"There's a lot of new-age stuff flying around but it's the basic skills: catch well, have disciplined lines of bowling and learning to sell our wickets a little more dearly than we do."
Two players Wright liked the look of, and he felt had something to offer - batsman Dean Brownlie and young seamer Doug Bracewell - had big series.
"For me, it's a feel," Wright said of picking the two Bs, when others may have had stronger form credentials.
Brownlie was New Zealand's best batsman, averaging 65.33; Bracewell's six for 40 on Monday was a match-winning effort of sustained aggression and accuracy.
He didn't get the man of the match award - it went to Australia's pugnacious opener David Warner for his fine, unbeaten 123 on Monday. It was made on a public vote, overseen by a sponsor and therefore a popularity contest and as such wholly without merit.
Warner's was an outstanding innings; Bracewell decided the test.
"Doug was really magnificent. His discipline of length and line paid dividends because if you got it in the right place the wicket would do something.
"He's uncomplicated, a strong lad for his age and he's had that cricket background from the start."
He has more answers about his players after this series. "This is a big win for us and we'll go into our next test knowing a little more about the players."
