''We are looking forward to the challenge. It will be a high pressure environment and we know that we will need to be at our peak to get the results needed.''
To that end, New Zealand are travelling to South Africa via Belgium. It may sound an odd route but the preferred option, via Perth and a handful of games against world No 2 Australia, fell through.
Plus Brussels, is hosting the women's league semifinal, which the New Zealand squad will be attending, around the same time.
The Belgians are world No 5, and were Rio Olympic silver medallists. The country is in the same time zone as Johannesburg, so there are pluses. New Zealand will have three matches against Belgium, which will certainly help.
Smith wanted tough preparation and he'll get it there. They have several days in Johannesburg to top off the lead-in into the tournament.
The squad are just back from eight days training at the Gold Coast, using the Commonwealth Games venue for next year. They'll have a fortnight together in Auckland before departing on June 23.
Smith liked what he saw from the younger players who went to the Azlan Shah tournament in Malaysia in April.
''We were keen to see how the young guys would match up against the boys returning from Europe and put them through some real competition,'' Smith said.
''We were really happy. Getting some of the guys back from Europe was really good, with their experience and some of them for the first time since Rio. It's nice to see them back in the squad.''
Among those ruled out of the trip are regular captain, world class striker Simon Child, who is sidelined by a lingering leg injury, Blair Hilton and James Coughlan, who was unavailable.
The Black Sticks will play Australia, Spain, Japan and France in pool A, starting with the improving French on July 9. Pool B comprises Belgium, Rio bronze medallists Germany, reigning African champions South Africa, Ireland and Egypt.
Ten teams are also taking part in the other semifinal tournament in London. Results over both tournaments will determine the teams to advance to December's world league final, to be held in Bhubaneswar, India.
The top 10 overall get qualification for the World Cup late next year, and also in the Indian city.
