Commerce Commission

Telecommunications Act 2001

Decision to Investigate Application for Determination for Number Portability Services

On 26 March 2003, an application was made under section
31 of the Telecommunications Act 2001, for the Commerce
Commission to determine terms under part (b) of that
section for both local and cellular telephone number
portability services.

On 30 June 2003, the Commission issued its decision to
investigate the application for both services.

Pursuant to section 35 (c) of the Act, the Commerce
Commission gives public notice that it has decided, under
section 35 of the Act, to investigate the application.

A public copy of the decision can be viewed or downloaded
from the commission's web site at:

Environmental Risk Management Authority

Hazardous Substances and New Organisms Act 1996

Determination of Hazardous Substances

Pursuant to section 26 of the Hazardous Substances and New
Organisms Act 1996, the Environmental Risk Management
Authority hereby determines the following substances are
not hazardous:

• Fluoropolymers, a class of polymers analogous to
  polyolefins in which some or all of the hydrogen
  atoms have been replaced by fluorine (and possibly other
  halides). Further, the definition is limited to those
  fluoropolymers (not containing additives) with a number
  average molecular weight greater than 10,000 amu and
  with residual monomer, catalyst and solvent impurities
  present at levels less than 0.1%. In addition, polymers
  that are cationic (or potentially cationic) or those that are
  water absorbing are specifically excluded from this
  definition.\n

• Polyethers, a class of polymers made up of monomer
  units linked by recurring ether linkages. For the purposes
  of this determination, no heteroatoms may be present
  other than the oxygen atoms involved in the ether
  linkage. Further, the definition is limited to those
  polyethers (not containing additives) with a number
  average molecular weight greater than 10,000 amu and
  with residual monomer, catalyst and solvent impurities
  present at levels less than 0.1%. In addition, polymers
  that are cationic (or potentially cationic) or those that
  are water absorbing are specifically excluded from this
  definition.\n

• Polyamides, a class of polymers that have recurring
  amide groups as an integral part of the main polymer
  backbone. For the purposes of this determination, no
  heteroatoms may be present other than those comprising
  the amide linkage. Further, the definition is limited to
  those polyamides (not containing additives) with a
  number average molecular weight greater than 10,000
  amu and with residual monomer, catalyst and solvent
  impurities present at levels less than 0.1%. In addition,
  polymers that are cationic (or potentially cationic) or
  those that are water absorbing are specifically excluded
  from this definition.\n

• Thermoplastic polyesters, solid polymers with recurring
  ester groups as an integral part of the main polymer
  backbone where no heteroatoms may be present other
  than the oxygen atoms involved in the ester linkage.
  Further, the definition is limited to those polyesters
  (not containing additives) with a number average
  molecular weight greater than 10,000 amu and with
  residual monomer, catalyst and solvent impurities
  present at levels less than 0.1%. In addition, polymers
  that are cationic (or potentially cationic) or those that
  are water absorbing are specifically excluded from
  this definition.

• Polyolefins, fully saturated hydrocarbons comprising
  only carbon and hydrogen with no other functional
  groups present. Further, the definition is limited to those
  polyolefins (not containing additives) with a number
  average molecular weight greater than 10,000 amu and
  with residual monomer, catalyst and solvent impurities
  present at levels less than 0.1%. In addition, polymers
  that are cationic (or potentially cationic) or those that
  are water absorbing are specifically excluded from
  this definition.

• Vinyl polymers (either homopolymers or co-polymers)
  made from the following monomers:

  • Vinyl chloride
  • Vinylidene chloride
  • Esters of acrylic or methacrylic acid
  • Styrene
  • Vinyl acetate (and its vinyl alcohol hydrolysis product)
  • Acrylonitrile
  • Butadiene
  • Ethene

  Further, this definition is limited to those vinyl polymers
  (not containing additives) with a number average
  molecular weight greater than 10,000 amu and with
  residual monomer, catalyst and solvent impurities present
  at levels less than 0.1%. In addition, polymers that are
  cationic (or potentially cationic) or those that are water
  absorbing are specifically excluded from this definition.

• Polycarbonates, defined as polymers made up of
  monomers (aliphatic or aromatic) linked by repeating
  carbonate units along the polymer backbone. For the
  purposes of this determination, no heteroatoms may be
  present other than the oxygen atoms involved in
  the carbonate linkage. Further, the definition is limited
  to those polycarbonates (not containing additives)
  with a number average molecular weight greater than
  10,000 amu and with residual monomer, catalyst and
  solvent impurities present at levels less than 0.1%. In
  addition, polymers that are cationic (or potentially
