Waikato police are now seeking sightings of four dirt bikes in their pursuit of Tom Phillips, following three sightings of him in Waikato last week.
Police want to hear from anyone who has spotted a Honda 50cc motocross bike, a 200cc black Suzuki Trojan, a 200cc Honda XR and a Honda 2008 FourTrax quadbike. They also want to hear about any historical sightings of a bronze-coloured Toyota Hilux ute.
Inspector Will Loughrin said the community can expect to see an increased police presence in the wider Marokopa and southwest Waikato area while they continue to search for the family.
