Tonga play tests against Georgia, Samoa and Fiji next month as they continue preparations towards the 2019 World Cup in Japan.
Head coach Toutai Kefu named six new caps in his 29-man squad, which will hold a week-long training camp in South Auckland from Sunday.
"This has been in the pipeline for a while and we've been able to secure some extra funding to make this happen so we're very lucky. If we didn't have that funding it would have been just the usual one week preparation for that Georgian test so to have that extra week is vital."
