First time international travel and it's in NZ

Hi! Just wanted to ask if anyone here has been in a similar situation or has experience with PH Immigration.

I already have an approved New Zealand Visitor Visa and will be traveling to NZ this September for around 7 weeks. I also have a confirmed return ticket to the Philippines.

My situation is a little unusual because I’ll be traveling together with my girlfriend, who is an NZ Permanent Resident. She currently works remotely and spends time between PH and NZ, and we’ll be flying to NZ together. I’ll also be staying with her/family during my visit, then I’ll return to the Philippines in October.

I’m currently employed full-time and have been with the same company since 2016. Since my work is fully remote, I can continue working while I’m in NZ. My NZ Visitor Visa also allows remote work for an overseas employer.

My employer doesn’t issue traditional payslips/payroll, but I have an employment letter from the company/CEO confirming my employment and explaining their compensation setup, plus supporting records if needed.
