How long it runs beyond that remains to be seen but the 39-year-old former first-class seamer, who did stints with Western Australia, Tasmania and Queensland, is relishing the chance.
"This is an opportunity for me to work in other areas and keeps me in touch with the latest areas of preparation and playing at international level," he said. "It's good for me, works for the Black Caps and, if all goes well, we'll look at it at the end of the African tour."
Jurgensen has an advantage in having worked with several New Zealand players in his first stint who have matured into senior figures. He also believes he's learned bowling skills in his time with Bangladesh which can enhance New Zealand's slow bowlers' work.
"There are new deliveries I've learned in the sub-continent. That's something I'd like to bring to the table, working with spinners.
"The squad has quite a few spinners with the T20 World Cup. I hope my experience there will be a benefit to the team."
New Zealand lost seamer Doug Bracewell today for the second test, starting in Christchurch on Saturday. His right shoulder is giving him problems but, with Matt Henry and Neil Wagner vying for his spot, no other player has been brought into the squad.
The options for New Zealand are straightforward - they pick one of Henry or Wagner as a straight replacement or play both and omit offspinner Mark Craig, who has been treated roughly by Australia's batsmen all summer.
For left-armer Trent Boult, New Zealand need to learn from how the Australian bowlers did their job in the innings and 52-run win in the first test in Wellington.
They were more demanding, notably seamer Josh Hazlewood and offspinner Nathan Lyon, than New Zealand's bowlers.
"They're the best team in the world for a reason and that's what you play for, to play the best teams and perform against the best players," Southee said. "We've been in this situation before so we're looking forward to hopefully levelling the series in a few days' time."
Boult expects the Hagley Oval pitch to be green - coach Mike Hesson called for an even greener strip than that for the first test, which settled down to a nice batting strip by late on the first day, as Australia prospered.
"It definitely swung around there nicely," Boult said of New Zealand's one previous test at the ground, a convincing win over Sri Lanka late in 2015.
