New Zealand beat Jamaica 62-40 in Napier in the second netball test on Saturday night after leading 35-21 at half-time.
The Silver Ferns made a stronger start than they managed in their 23-goal win in Christchurch earlier in the week.
But with coach Ruth Aitken making changes at both ends of the court, new combinations took time to settle in the second half.
The Silver Ferns now have three tests against Australia before the Commonwealth Games.
