Adrian Rurawhe says he will now be looking to more "meaty" legislation after getting a member's bill passed in his first term in Parliament.
The Official Information Act (Parliamentary Under-Secretaries) Amendment Bill, brought to Parliament by the Te Tai Hauauru MP, passed into law last week after it was drawn from the member's ballot last year.
"Just getting a bill out of the ballot is one challenge and it's all luck," Mr Rurawhe said.
He inherited the bill when he came into Parliament in the 2014 election, with new MPs getting to pick up drafted bills from the previous term.
The act places parliamentary undersecretaries under the same Official Information Act obligations as Government Ministers when carrying out ministerial work.
