OneAdsphere + First Voice

One team for marketing, websites and AI that answers every call.

OneAdsphere stays the brand
First Voice’s AI receptionist, speed-to-lead and chat agent join the line-up
For businesses in New Zealand and Australia

The short version

OneAdsphere, the Auckland marketing agency, and First Voice (FirstVoice AI), the New Zealand AI receptionist service, have merged. OneAdsphere remains the brand. First Voice answers business calls 24/7, books appointments and calls new leads back typically within 60 seconds; OneAdsphere runs marketing, websites, SEO and the Pickup System. Together they serve businesses in New Zealand and Australia.

Why it fits

Marketing creates enquiries. Too many die on the phone.

A call at 7:40pm that rings out. A form filled in at 9pm that nobody calls back until morning. OneAdsphere built the front of that journey; First Voice built the part where the phone rings. Together, one team is accountable from the ad to the booked appointment.

Two Wellington garage door companies. More than 1 in 4 calls came outside business hours, and 1 in 8 on a weekend: calls that would otherwise have gone to voicemail. First Voice answers for both companies, day and night, takes the caller’s name, number, address and what’s wrong with the door, and passes every enquiry to the team.

How we know

How First Voice counted: Figures from First Voice’s own call records. Business hours are 8am to 5pm, Monday to Friday, NZ time. Appointments are counted only where the booking system confirmed the booking. A lead counts as reached when the conversation lasted more than 15 seconds. Client names are withheld. Source: firstvoice.co.nz/results.

Checked 12 Oct 2026.

I am using FirstVoice to call my leads as soon as they come in from Meta. The potential clients love that I contact them quicker than anyone. I am able to close more deals because I'm the first to them.
