"Kruger's made a lot of sacrifices to try to make it into the national team ... so what we've got is a lot of internal competition between two great men,'' he said.
"You know that whoever ends up starting will bring an exciting spirit and attitude.
"You've got to weigh up whether you're happy with BJ doing the job or whether we give him more time and let Kruger have first opportunity.
"They both understand that the best man will play and that's what we're trying to do in all our positions - create more competition.''
Wright added he was looking for his batsmen to adapt the appropriate mindset for the test after a heavy diet of Twenty20 cricket over the past month.
"It's something we have talked about so it'll be challenging for them because they have been playing that for a month now.''
One positive was the batting form of Brendon McCullum, Martin Guptill and Dean Brownlie, who have all hit centuries in the recent HRV Cup competition.
"Those three come in to give us some sort of opportunity to cash in on ball striking. In the end, it's the balance of working out how to play five-day cricket, which is, you know, hitting the right shots at the right balls,'' Wright said.
The McLean Park wicket is expected to favour the batsmen which could present a challenge to the Zimbabwe attack which made few inroads into the New Zealand XI's batting order yesterday.
"If you are a batsman and you want to make some runs, then Napier isn't a bad place to be,'' Wright said.
