More sex charges laid against cricketer Jason Trembath

District representative cricketer Jason Trembath will face an extra nine charges of a sexual nature after alleged attacks on as many different women, police say.

The attacks occurred in public in Hawke's Bay and Rotorua between September and November 2017.

Mr Trembath was already facing charges of sexual violation and indecent assault after he allegedly attacked two women in Napier and Havelock North on November 5 last year.

The 29-year-old appears in Napier District Court on Friday morning.

Mr Trembath had played at district level in a number of cricket sides, including Taradale in Hawke's Bay and Central in Rotorua.

Hawke's Bay Area Commander Inspector Dave Greig said the victims' courage in reporting the attacks, despite the unsettling nature of the incidents, assisted their investigation.

"We also want to thank the wider community for their assistance during this investigation," he said.

"The investigation team have worked diligently to gather evidence in respect of each reported attack, and while we are very pleased with the progress made to date, the investigation remains active.

"We urge anyone that may have experienced something similar in Hawke's Bay or Rotorua, but not yet reported it, to contact us."

Hawke's Bay Police says the victims have each been provided with support, and assured the community it had "taken these events very seriously".

Those with information are urged to contact Hawke's Bay CIB on (06) 211 3872 or Crimestoppers on 0800 555 111.
